The former Everton midfielder is set to become a free agent at the end of this month after the defensive star allowed his contract to run down at Old Trafford.
Belgian midfielder Fellaini has been linked with a potential move to their Premier League rivals Arsenal in the summer transfer window.
The 30-year-old would certainly fit the profile of player that Unai Emery is targeting this summer following the additions of veteran Switzerland international Stephan Lichtsteiner and Bayer Leverkusen goalkeeper Bernd Leno.
However, reports on Thursday suggested Fellaini was set to commit to a new contract with the FA Cup and Premier League runners up.
Belgian reporter Terreur confirmed that Fellaini is set to put pen to paper on a new two-year deal with the Red Devils this summer.
“His new contract at Man United is ready to sign,” Terreur told the Transfer Talk podcast.
“It will be two years with an option. He is willing to sign it. So he will stay for two more years.”
Fellaini has won the FA Cup twice and the Europa League during his five-season spell at Manchester United.
The Belgian star moved to Manchester United in a £27m deal from their Premier League rivals Everton in the 2013 summer transfer window when his ex-Toffees boss David Moyes was in charge of the Red Devils.
