Cardiff City boss Ole Gunnar Solskjaer admits he's preparing to face Juan Mata in Manchester United's line-up tomorrow night.
The playmaker completed his switch from Chelsea on Saturday for £37.1million.
Regarding the Spain international, Solskjaer joked: "I think he will have to wait until next weekend to play for United - well, hopefully he will!
"He is one of the top players in European and world football. He has done fantastically for Chelsea over the last few years. United have signed a top, top player."
