An injury crisis at the start of the season forced Louis van Gaal to throw McNair in at the deep end but the youngster wasn’t fazed and impressed at the back despite usually playing in midfield.
With the departure of Danny Welbeck last summer, Man United fans were delighted to see ‘one of their own’ in the starting XI.
Irwin has been impressed with how quickly McNair has settled in at Old Trafford and is delighted Man United agreed a new deal with him.
Speaking about McNair, Irwin said: “All the way through the ranks he’s played in midfield, except probably last year in the under-21s when he played as a centre-half,” Irwin said.
“Because of the defensive injury problems we’ve had, he was thrown into the deep-end in the first-team, but he’s handled it very well.
“He had a tough moment away at Southampton away, but I thought the manager was great in the next game against Liverpool, when he made him sub and brought him on at the end. That did his confidence the world of good and he played really well at right-back against Cambridge United.
“He’s a good footballer – you can see that. Again, he’s at an age when he’s going to get more and learn more. It’s great he’s been given a new contract and it shows the strides he has made in the last six months.”
McNair has had his shaky moments but that could be said of the whole team this season. Aged just 19, McNair has a long future ahead of him.
