We speculated Sir Alex Ferguson would have a trick up his sleeve in his team selection last night, but we didn't quite guess it would be Danny Welbeck.
In recent weeks the striker has been deployed out wide and in a withdrawn role, and we now know why, he had been identified for this role in the Bernabeu.
The England forward scored the opening goal of the game, United's crucial away goal, as the game finished a 1-1 draw.
His impact proves he belongs on the big stage, and makes a mockery of reports in January which linked him with a loan move to Reading.
Welbeck played 73 minutes, but with perhaps the exception of David de Gea, was United's star man last night, as 'up for the tie' as any other player on the pitch.
As well as scoring the header, it was his defensive contribution which really marked him out. He made the joint highest number of tackles as any United player on the pitch with four, equalled only by Michael Carrick.
He certainly did his job and more and it looked like a tactical masterstroke by Sir Alex.
Here is a selection of what United fans were saying about Welbeck on twitter in the wake of his performance.
@insidesafstand: Fantastic performance. For me, Welbeck's best performance in a
@lipski7: MOM -Welbeck for me. He was immense. Has his doubters (bizarre!). De Gea close runner up. Jones 3rd
@eadzzzzz: Welbeck MOTM for me had a blinder not pretty but really effective good to see a Manc lad playing for his hometown club
@joshlee123: 1-1. Professional performance. Outstanding from United. Welbeck was immense.
@tomgreen2608: Any more arguments against Welbeck for England?
@adam_jones89: Honourable mention for Danny Welbeck. Has been frustrating at times this season, but he ran RM (and himself!) ragged tonight. Top boy
