After Rooney U-turn, Man Utd to push through Defour deal
Defour has been a long-term target for manager Sir Alex Ferguson, who will offer £12 million for the midfielder in January.
Ferguson is expected to ramp up his transfer plans after securing Wayne Rooney's signature to a new contract.
Owen Hargreaves has not started a game in two years and Ferguson wants to add some bite in midfield having seen the former Bayern Munich star struggle to battle back from his chronic knee problems.
Belgium international Defour, 22, is the man Ferguson wants as his midfield lynchpin and Liege are willing to listen to offers, with United ready to start the bidding at £12m.
