Manchester United are keeping tabs on Aiden McGeady's situation at Celtic.

The Daily Record says the latest rift between the pair was behind manager Gordon Strachan's decision to bench the winger for Sunday's emphatic win at Motherwell and the Champions League clash with Aalborg.

Strachan has been growing increasingly concerned with McGeady's form since the start of the season and is determined to get the player refocused on playing the kind of football which wowed supporters last season.

But sources close to the player insist McGeady is so furious at the snub he may even be considering his future in the knowledge he would have no shortage of suitors in the January transfer window, including the likes of Newcastle, Spurs and possibly even Manchester United.
