Jose Mourinho says an agreement is "almost" in place for Marouane Fellaini to extend his contract at Manchester United.
The 30-year-old Belgium international's deal at Old Trafford expires at the end of the season, meaning he is able to negotiate a free transfer away from United.
Fellaini's stoppage-time header gave United all three points against Arsenal in the Premier League on Sunday, and Mourinho is keen to keep his match-winner at the club.
Following the victory - which guaranteed United a top-four finish - Mourinho was asked about Fellaini's future, and said: "The position is that we are almost there.
"But in football, the almost is not enough. I think we are almost there, but I can't celebrate because almost is not enough.
"I want to see the white paper with the United crest, Ed Woodward's signature and Marouane's signature."
Fellaini was signed by former United boss David Moyes from Everton in September 2013, and has gone on to score 19 goals in 154 appearances for the Old Trafford side.
