This is a transformative summer for Newcastle in terms of transfers ahead of a big season for the club - with lots of new faces.
It has been long discussed that multiple changes are expected within the Newcastle squad this summer - as many as eight, nine or 10 positions could be affected.
Newcastle have already sold Anthony Gordon and Sandro Tonali to Barcelona and Tottenham respectively - and they do not want to lose captain Bruno Guimaraes, but there is a question mark over his future amid his desire to join Arsenal.
Sky Sports News' North East reporter Keith Downie answers all the big questions hovering over St James' Park...
What is the latest on Bruno Guimaraes' future?
Bruno Guimaraes has not handed in a transfer request at Newcastle.
What he has done is he's spoken to Newcastle directly and said that if an acceptable offer, a good offer comes in from Arsenal, he would like to pursue that opportunity.
That is for footballing reasons, not money reasons. He's Newcastle's highest earner and has really good wages at Newcastle. He would probably earn slightly more at Arsenal, but not a whole lot more.
At 28 - he turns 29 later this year - he wants to win titles. He doesn't believe that is going to happen at Newcastle over the next couple of years, both on and off the pitch. He would like to be given that opportunity to join Arsenal.
But Bruno wants to ensure that if he does leave, Newcastle get a high fee for him.
The tipping point for Newcastle would be around about £80m. If Arsenal offered that, Newcastle would have to sit up and listen.
But Arsenal have yet to make any contact with Newcastle over his availability. Newcastle are flabbergasted that there has been talk of him leaving when there has been no contact whatsoever from Arsenal. Everything has been driven through agents.
Until a concrete offer comes in, Newcastle do not have a question to answer. They are desperate to hold onto him - and see him as not for sale.
Will Newcastle's Manzambi deal get over the line?
Newcastle have an agreement in place to sign Johan Manzambi from Freiburg for £49m - he is one of their top targets this summer.
A delegation went to Germany to meet with Freiburg this week and verbally agreed the deal. The player has also verbally agreed personal terms.
But he is still competing for Switzerland at the World Cup. And until a contract is signed, Newcastle remain cautious - with the memory of Victor Munoz fresh in the mind from a few weeks ago: Liverpool came in and hijacked that transfer at the very last minute.
Newcastle are remaining very cautious on this one but are confident they have a deal in place. Manzambi has said he will not commit to any contract until after the World Cup. He's nursing a slight knee injury at the moment but Switzerland are through to the quarter-finals so Newcastle have to wait until they are eliminated.
It's bit of a nervy time for Newcastle - there is a worry that another club could come in. But they have done all the work they can do to ensure Manzambi is a Newcastle player next season.
And he looks like a good player, too: five goal involvements at the World Cup, the best record of any player of his age since records began.
How many signings will Newcastle make?
Three or four more signings are expected after a deal is done for Manzambi. Beyond that, they are still looking at another midfielder - potentially in the event that Bruno leaves.
They are also looking for a No 1 goalkeeper to come in - and have a long-standing interest in James Trafford. Moves are expected for the Man City goalkeeper in this window.
They are also looking for a full-back who can play either right-back or left-back - but preferably left-back.
They might look to bring in another winger if Jacob Murphy potentially leaves. Potentially a striker too if they lose one of Nick Woltemade and Yoane Wissa.
If neither goes, they would go with the three strikers they have for next season - Wissa, Woltemade and Will Osula.
What is Newcastle's new transfer policy?
The transfer plan is to remain within their current framework of signing players between 18 and 24 - and within a price tag of £20m and £40m.
They could still pick up players below that fee - such as Ewen Jaouen who has arrived for £18m - and they have an agreement in place with Freiburg for Manzambi at £49m. So they're pushing the boat out for that player.
They are willing to slightly go beyond their rules - but not by a huge amount. Don't expect Newcastle to spend £80m, £90m or £100m on a player. This is a new way of working: cheaper players, younger players, but ones with a high ceiling that Eddie Howe can improve on the training ground.
They are looking more towards the model of Borussia Dortmund - bringing young players in, moving them on in the future and still trying to compete for titles and trophies while doing that.
Who could leave the club?
Nick Pope is expected to leave. There was interest from Ipswich but that has gone away for him.
There is a chance Murphy could leave after being there for a decade. Joe Willock could depart, too.
There is no offer on the table for any of those three but Newcastle would look to shift these players out in order to totally revamp the squad. These are the ones they would be content to lose this summer.
But if Pope, Murphy and Willock were all to go, Newcastle would need to replace them as well.
Will Sean Steur walk straight into the team at 18?
No. He's very much seen as a signing for the future. He will be given opportunities and will train with the first-team squad, but he's expected to be a substitute to start with - and then will be given the chance to try and work his way into the team.
What will work in his favour is Newcastle do not have European football next season. He will benefit from a full week of work on the training pitch with Howe every week. There will need to be progress in his physicality - and adaptation to the Premier League.
He doesn't walk into the starting line-up, but maybe this time next year he could be in regularly. This type of signing is what Newcastle are looking at in the future. They are not looking for ready-made Premier League players, they feel they have enough of that already.
What does Howe think of all these changes?
Howe is on board with this change in model. Himself, the sporting director Ross Wilson and the chief executive David Hopkinson are all on the same page. Howe knows things need to be different from last summer - which saw a disastrous window.
They spent £250m and a number of the signings did not work. The Alexander Isak situation left a could over the season - they don't want to wait until the last minute and want everything done early.
Howe is on board with bringing in younger players who he can improve on the training ground. That is what he does best. He will see this as a real opportunity to improve players like Steur, Bazoumana Toure and Manzambi. Everyone is excited by the prospect of it.
There is no European football - and while they would love to be in, not having midweek games which lead to so few training sessions will actually help.
The team will be fresh every week, with a lot less pressure. That should help the new players bed into the team and be better. Providing they all hit the ground running to an extent, Newcastle could have a good season.
Will they finish in the top four or five? Probably not. But they could finish in the European places. Not being in Europe will give them a good advantage.
Is the Saudi PIF still committed to Newcastle?
Saudi Arabia's Public Investment Fund (PIF) is still committed to Newcastle - there is assurance in that. But there are question marks when the fans and outsiders see Tonali, Gordon, Isak - and potentially Bruno - all leaving to pursue new ventures with bigger football clubs.
That's where Newcastle are. They're finding it very difficult to break into the top six, with the financial rules restricting them. They're looking to get beyond that with smart recruitment and learn from the past.
They can also do that by increasing their commercial revenues, which are around half of the so-called 'big six' clubs. If they increase their revenue streams, then they can start competing with these clubs in terms of transfer fees, wages and signing players.
There is work to do and that is an area where Newcastle have been a little bit slower than expected. It is improving year on year, but not at a fast enough pace to compete with the big clubs. A new stadium would help massively, and more sponsorship deals too.
The owners are still putting everything they can into the club in terms of transfer money. They recently made a breach of PSR and were fined as a result of that. They don't want a repeat, so they will spend as much money as they can.
