Manchester United captain Wayne Rooney has denied any knowledge of Jose Mourinho's imminent arrival at Old Trafford despite widespread reports the Portuguese coach is preparing to replace Louis van Gaal. Victory over Crystal Palace in the FA Cup final at Wembley was followed by speculation that Mourinho to ready to return to the sport, less than a year after he was sacked by Chelsea.

BBC Sport understand United will announce next week that Mourinho is to become the club's new manager having told Van Gaal he is surplus to requirements after failing to guide the club into the Champions League. Securing a record-equalling 12th FA Cup, the club's first since 2004, was the Dutchman's first major trophy in charge however it appears it has come too late to ensure he stays for a third season.

The reports worked to overshadow a final which was won in extra time by Jesse Lingard's stunning volley, after Jason Puncheon's goal had been cancelled out by Juan Mata's strike. United skipper Rooney was asked to comment on the story following the game but refused to be drawn on the rumour.

"I know nothing at all," the United forward told Sky Sports. "That's a question for Louis van Gaal or Ed Woodward. It's nothing to do with me. I don't want to speak about how Louis van Gaal has been because he's still our manager and he's still in his job.

"I think it's unfair after he's led us to win the FA Cup that we speak about him as if he's not here. I think he's a good manager and we are grateful for him helping us win this FA Cup. It's down to him or Ed Woodward to decide what happens."

Van Gaal still has one year remaining on his current deal at United but failure to secure a top four finish, coupled with a group stage exit from the Champions League and an inability to challenge for the title has contributed to his downfall. The ex-Barcelona and Bayern Munich coach has spent in excess of £250m during his two campaigns in charge but results have barely improve since the ill-fated reign of David Moyes.
