Jonny Evans recently returned to action after a period out injured.
Manchester United have had it tough this season regarding injury problems. Especially at the back they have had a long list of injury worries, with the likes of Phil Jones, Chris Smalling and Marcos Rojo just a handful of their difficulties.
This has seen the likes of Michael Carrick and Daley Blind play at centre-back this season and Tyler Blackett and Paddy McNair play more football than they would have anticipated this season.
But they have been boosted this week by the return to fitness of Jonny Evans. The Northern Irish defender returned during the game with Southampton on Monday night, his first appearance since the disaster against Leicester City earlier in the season.
His return is great news not only for Manchester United, but also Northern Ireland.
"I was really pleased for Jonny when he came on against Southampton because he has had such a frustrating time. They struggled a bit to solve his problem and he was out for longer than he anticipated so he will be relieved to be back.
"I thought he did well at Southampton after a long spell out. Hopefully now he will get a run. I believe United need him.
"I think what Jonny has is what Louis Van Gaal likes in a defender. He has great mobility, can bring the ball out of defence and is comfortable playing in a back three or a back four. It doesn't faze Jonny to play in any of the positions in a back three which is a good quality to have.
"He's also been waiting for his chance to really impress Van Gaal. In pre-season things were going well and then the injury came at a bad time and now he deserves a bit of good fortune and getting a number of games under his belt."
Evans is expected to play against Liverpool tomorrow afternoon and O'Neill is confident he will do the trick against United's arch-rivals.
"I saw him play against Liverpool in the League Cup last year and he had just come back from injury. It was actually Luis Suarez's first match back from a long suspension and Jonny handled it brilliantly."
United fans will be hoping that his national coach is right about his return.
