Skysports.com understands Manchester United are weighing up a move for long-term target Steven Defour.
The Standard Liege midfielder has attracted the interest of United in the past with United boss Sir Alex Ferguson even sending a letter to the player last year to wish him a speedy recovery after he suffered a serious foot injury.
A number of clubs across Europe have been credited with an interest in Defour, but United are keen to lure him to Old Trafford.
In a bid to steal a march on their rivals United could step up their interest in the Belgian international befoe the close of the transfer window.
Defour has previously expressed his desire to move to England and United could be in the market for a new midfielder as doubts continue to surround the long-term future of Owen Hargreaves.
