After a awful start to the season that ended any Premier League title hopes early on, and an early Carabao Cup exit at the hands of Frank Lampard's Derby County, the FA Cup presents the only real shot at silverware for United this season. Valencia would like to sign the 19-year-old permanently but there has always been clamour among the United fans to see him given an opportunity.
The nature of the festive calendar has meant that the Norwegian has already overseen five games, winning all of them.
Lukaku scored for the third game in a row but Sanchez, starting a game for the first time since Nov.7, was forced off with a hamstring injury.
The run of results has seen United move back in to contention for a top four finish in the Premier League but it's cup matters at hand this weekend as the Manchester giants look to book their place in the fourth round of the FA Cup.
Instead, Man United were a bit too relaxed for this occasion.
Lukaku credits Solskjaer with helping him return to form and explained how the coach approached him when they first linked up at United.

With a week until kickoff against Tottenham, Manchester United have flown to Dubai to train.
Cup holders Chelsea and record 13-time winners Arsenal were among the other Premier League teams to progress to the last 32. 2-0 flatters us because I think they played some great stuff, then again we could have had three or four towards the end.
All of a sudden the Old Trafford garden is a green one. Swift give the ball away and United counter quickly.
After some good play, United had the ball in the net through Fred but it was ruled out for offside.
It was left to fellow Spaniard Alvaro Morata to score in the 49th and 59th minutes, with the striker set up both times by crosses from 20-year-old winger Callum Hudson-Odoi.
