Fellaini has become a key player for Jose Mourinho at Old Trafford this season, helping the Red Devils to two trophies and the Community Shield over the course of the campaign.
The Belgium international has had some big moments along the way, including goals in the Europa League and EFL Cup semi-finals, and even captained the side against Sunderland, report the Manchester Evening News.
But, when asked if he would ever be tempted to follow in the footsteps of compatriot Axel Witsel, in moving to China when the window reopens on June 19, Fellaini was keeping his options open.
“In China? Why not?” he told VTM News .
“I’m now Manchester United player, but I do not rule out such a transfer in the future.”
Signed by David Moyes on deadline day in 2013, Fellaini has proved a divisive figure for United’s fans.
A section of the Reds’ support even booed him as he came on against Tottenham in December – a week after he gave away a penalty at Everton.
Mourinho has continued to stand by him, though, and even took up the option of triggering a new one-year contract extension in January.
And Fellaini has explained the simple reason why he was thrived under the Portuguese.
“He knows how to use me. At the start of the season, I played as a No.6, then as a No.8 and then a No.10. I play wherever he needs me,” he added.
“He knows my qualities and knows how to use me. If he plays me, I will play there and give my best.”
