Manchester United midfielder Marouane Fellaini is in advanced negotiations with another top Premier League club, believed to be Arsenal.
The Belgium international is edging towards leaving Old Trafford after strong interest from the north Londoners.
The 30-year-old is out of contract at the end of the month and will be able to walk away for nothing.
United boss Jose Mourinho has stressed for much of the last year that he is keen to keep Fellaini at the club - but he started just two league games since the turn of the year.
Speaking after Fellaini came off the bench to score a last-gasp winner against the Gunners in April, Mourinho said: "I want to see the white paper with the United crest and Ed Woodward's signature and Marouane's signature."
Fellaini, who is part of Belgium's World Cup squad, joined United from Everton in 2013 but has failed to hold down a regular place in recent times.
Now he is edging towards the exit as he talks to Arsenal, with new boss Unai Emery believed to be ramping up his efforts to sign him as he prepares for another season in the Europa League, although a new deal at United remains on the table should Fellaini opt to stay.
