Vitor Pereira believes Nottingham Forest were unlucky to come away from their match with Liverpool empty-handed after conceding a heartbreaking 97th-minute winner.
Alexis Mac Allister popped up with the all-important goal in the closing stages at the City Ground, having previously had a potential winner ruled out for handball in the 89th minute.
However, Forest had been on top in the first half, having 12 of their 18 shots before the break, but failed to test Alisson thereafter as Liverpool grew into the game.
Their 12 first-half attempts were the most any side has managed in the opening 45 minutes of a Premier League game against Liverpool since Stoke City in May 2015 (also 12), though the Potters were 5-0 up at half-time that day.
As for Pereira, he became the first manager to lose his first Premier League game of a spell in charge of a club due to a 90th-minute (or later) winning goal since Nuno Espirito Santo also did so with Forest against Bournemouth in December 2023.
"We are very frustrated. The way we played the first half was by creating chances and not conceding anything," Pereira told BBC Sport.
"It was a fantastic first half. We know the second half could be difficult because we played three days ago and travelled four hours. We didn't press properly. They won the game. In my opinion, one point was the minimum. Zero points is not fair.
"Inside the pitch, we must put the tallest guys where their tallest guys are. That must happen inside the pitch. We didn't. We lost the game in a small detail, but we know we need to correct these kinds of things. It's a pity.
"The supporters were with us until the last minute, and they recognised we deserved more than this, but that is football. We need to prepare ourselves mentally and tactically for the next game.
"The team has talent. The players have ambition and talent. I am confident we will get points until the end of the season to move forward. One point is better than nothing. We have to come back stronger."
Forest remain just two points above the relegation zone, having missed the chance to leapfrog Tottenham with a win.
