When quizzed on whether that club was the Red Devils, Moyes said that United were always looking at the finest talent from around the world.
"Manchester United is always interested in the best players," Moyes told Sky Sports News.
"The owners have given me every opportunity to bring in whoever I want and we're always looking at the best players. Unfortunately, it hasn't worked out too much so far [in the transfer window].
"I can't give you any more than that right now."
Moyes was speaking after his side's 0-0 draw at home to Chelsea this evening.
