The Reds are in dispute with Man Utd and no-one knows where Heinze's future lies.
Baines snubbed the chance to join Sunderland in a £6million move recently and it all depends if the player is willing to hang onto hopes of moving to Anfield, or take Newcastle's offer, where he knows he would be just about guaranteed of a first team place.
But there could be another twist ... if Heinz does go to Liverpool, United are reported to be keen on the England Under-21 man and could be interested once Heinze's situation is clarified.
