Celtic have signed centre-back Jahmai Simpson-Pusey on a season-long loan from Manchester City.
The 19-year-old, who made six senior appearances for City last term, becomes Brendan Rodgers' seventh summer signing.
Simpson-Pusey, an England under-18 international, captained City to victory in the 2024 FA Youth Cup final and was brought into the first-team fold by manager Pep Guardiola last season when injuries hit his senior players.
He started in the Premier League and Champions League last season, but was not involved at first-team level from January and ended the campaign leading City in Premier League 2 to a play-off final victory over Southampton.
"He's a young player that I feel can come into this environment and really support us," Rodgers told Sky Sports News.
"With the number of games that we play, we need a number of centre-halves and he's one that his profile and attributes fit how we play.
"He's got good pace, he's a good defender first and foremost, but he can also play football because at Celtic you need to be able to build the game from behind and progress the game quickly and he can do that.
"I think he'll join the rest of the squad. As I said, he's a young player, he's had some senior games, not many with Man City, but he's had some senior games.
"He's had the trust of Pep [Guardiola] to put him in and now he comes here for a year and continues that education at a massive club."
Who else have Celtic signed this summer?
Kieran Tierney's return to Parkhead was the first confirmed summer transfer, after the defender agreed a pre-contract with his boyhood club.
Meanwhile, goalkeeper Ross Doohan is also back at the Hoops on a three-year deal after leaving Aberdeen.
Celtic have also signed Benjamin Nygren from FC Nordsjaelland in a deal worth around £2m, with the winger signing a five-year deal.
Twenty-three-year-old defender Hayato Inamura has joined from Albirex Niigata on a four-year deal and Shin Yamada has moved from J-League side Kawasaki Frontale on a four-year deal.
The club also secured the signing of teenage forward Callum Osmand on a free from Fulham.
