As such, the news emerging today - that Fellaini's representatives will meet with Arsenal ahead of the expiration of his contract on June 30 - will be met with mixed emotions from fans of the Red Devils.
Paul Hirst of The Times reported on Monday afternoon that Arsenal's interest in Fellaini is genuine and he is more likely to move to the Emirates Stadium than put pen to paper on a new deal at United. Last 15 minutes, "get him on".
Fellaini is out of contract at Manchester United at the end of the month and has been allowed to negotiate with other English clubs since Friday.

Arsenal are on a tight budget this summer after spending big on Alexandre Lacazette and Pierre-Emerick Aubameyang last season.
