Wayne Rooney is "angry and confused" over David Moyes' apparent comments that he sees the striker as back-up to Robin van Persie, according to Press Association sources.
Manchester United are remaining silent over the affair but the England international's future at Old Trafford is now in doubt, with Chelsea the bookmakers favourite to sign the forward.
The 27-year-old has no intention of playing second fiddle to last season's top scorer van Persie or being reduced to the rank of a squad player.
Rooney was sent home from the club's pre-season tour in Thailand after suffering from a hamstring injury.
