Manchester United have denied reports that an agreement has been reached in principle with Atletico Madrid's Antoine Griezmann.

Jose Mourinho's men have long been linked with a summer move for the 25-year-old and it has been reported in France that the basis of an agreement is in place with the attacker.

However, while Griezmann may be of interest to United, an Old Trafford source has denied Wednesday's reports, according to the Press Association.

There was no opportunity to ask manager Mourinho if he could comment on the report given his abrupt exit from the press conference following Wednesday's frustrating 0-0 draw at home to Hull.

However, in the pre-match press conference the Portuguese confirmed plans are afoot when it comes to summer planning, having recently been linked regularly to Griezmann and Benfica's Victor Lindelof.

"In our case, we are more focused on the summer period," Mourinho said hours before January transfer window shut. "I like my players, so nothing for me. I know what I want.

"I always think every week, the more I know my players, the more I know my team, the more I know the competition, because it's a competition I know really well, but it's a competition that is in permanent evolution.

"I know what I want, yeah. I know what I want. But the market closes today, so there is no point, especially for me, to speak about the next transfer window when we have so many matches to play, so many competitions to fight for and so many good players to work with.

"So if you ask me do I know what I want for the next transfer window? Yes, I know. Is it possible to get? I try always to be realistic.

"I remember many years ago when I was asking for a second goalkeeper, the technical director gave me a list of possible second goalkeepers and the first choice was (Gianluigi) Buffon to be my second goalkeeper.
