Chris Armas will return to Old Trafford with a point to prove tonight as he takes charge of Leeds United for the first time.
The former Manchester United assistant only arrived at the Yorkshire club last month, but has been thrown into the interim role after the sacking of Jesse Marsch this week.
Armas spent half a season with United last season and was infamously likened to the fictional football coach Ted Lasso before leaving along with Ralf Rangnick at the end of a dismal campaign.

The 50-year-old will no doubt want to prove that he really does have the credentials to make an impact in the Premier League on Wednesday which will give him the chance to pit himself against a man he has studied in Erik ten Hag.
Last summer, before the season had even started, Armas spoke about his own time at United and went on to predict the impressive impact Ten Hag would have on the club.
"I do think that there are a lot of good pieces in place already," he told Sky Sports last August. "I have studied his principles before. With the ball and without the ball, enjoy what he is looking to bring and sitting on the edge of your seat, enjoying attacking, possession-based and counter-pressing football, you can see it all in his game.
"But I do see a serious side to him; I don't think he is afraid to make big decisions and I don't think he is willing to relent on his principles in his way."
Ten Hag certainly hasn't been afraid to make the big calls during his time at the club, and he has also made a huge impact through the attractive style of football he has begun to implement.
Armas also went on to praise the new United boss for the summer signings he had made at that point and the vast experience they would add to the team.
He continued: "You can see with guys like Eriksen, these are culture guys that he has brought in. Making big signings is one thing, and you want to get them right, but part of getting it right is bringing in good footballers, but also guys that can affect and influence the locker room, on the pitch and off the pitch — and I think he is doing that.
"It is guys that can actually sway a locker room and lead. I think the challenge for him as that he needs a little bit of time."
