Sunderland boss David Moyes admits losing Patrick McNair for the season is a blow.

McNair is out due to a serious knee injury.

“Paddy was starting to understand more about the club, the supporters and also the general game, so it's a real shame for the boy," said Moyes to the Sunderland Echo.

“He's really keen to do well and he works really hard at his game to try to improve.

“We're incredibly disappointed because we want to try to build a young team going forward and Paddy was part of that.

“I think he'd just started to find his way in the Premier League – even though he had experience at Manchester United – and the games he was having were bringing him on and giving him confidence."
