Sir Alex Ferguson refused to confirm or deny his interest in signing Germany star Mesut Ozil following Manchester United's Community Shield victory.
United boss Ferguson was at Craven Cottage on Saturday, where Ozil's Werder Bremen side were playing Fulham in a pre-season friendly.
Ferguson hinted he was an admirer of the 21-year-old - one of the best players at this summer's World Cup - but asked if he was interested in bringing the playmaker to Old Trafford, he replied cryptically: "I don't know."
He added: "I think a lot of clubs would be interested in Ozil.
"At the moment, I think we've got a great squad. I don't need to add to it - that's my opinion. I trust them.
"But, as I said, there are a lot of clubs interested in him."
