Manchester United may consider offers for Marouane Fellaini this month.
AC Milan, Porto and clubs from China and Turkey have shown interest but have still to make firm bids.
Fellaini is also on a lucrative wage following his contract renewal last year.
The powerful midfielder was frequently used by former manager Jose Mourinho when the Portuguese wanted to change the game.
But under Ole Gunnar Solskjaer, United have deployed teams packed full of pace and dynamism perhaps lacking in the Belgian player.
