Manchester United boss Sir Alex Ferguson has warned of the threat of FA Cup opponents Reading.

Reading are up next this year, with an FA Cup fifth-round clash at Old Trafford on Monday.

And Fergie declared: "In many people's eyes 'it's Reading, yeah, we've just been to Madrid, it was a great night and Monday will take care of itself'.

"Monday can't take of itself. We have to take care of it, we have to have a performance which respects our opponents and the fact the FA Cup can produce shocks."
