Manchester United legend Sir Bobby Charlton has revealed that Wayne Rooney is 'happy' at Old Trafford and he has 'no doubt' that the forward can break his long-standing record as United's all-time leading goalscorer. The summer transfer window was dominated by speculation linking Rooney with a move to Chelsea after Sir Alex Ferguson suggested at the end of last season that the player had expressed a desire to leave Old Trafford. Reports then emerged later in the summer that Rooney was 'angry and confused' with life at United with Chelsea then seeing two bids for the striker rejected as new United boss David Moyes maintained his stance that Rooney would not be sold.
