“Most of the time we get to keep who we want to keep,” he said. “The longer it went on the more I got to speak to David and I was confident we would make it.
“David is delighted and I think you could see the focus in his eyes again against Leicester. It gives everyone in front of him a boost because you feel secure with him behind and he’s really worked hard this season. I’m sure he will be part of success at United.
“Obviously he’s signed his contract but Sergio will play on Thursday for sure. He’s proven to be a top, top ‘keeper behind David, so it’s time for him to have some much-needed game time.”
United were handed an injury boost ahead of the match with Jesse Lingard and Diogo Dalot returning to training.
However, Paul Pogba, Anthony Martial and Luke Shaw all remain sidelined, and summer signing Daniel James is also out after picking up a knock against Leicester on Saturday.
