ROONEY IN TROUBLE AGAIN

Wayne Rooney will be told by the FA: Stop turning the air blue.

Roo is back in trouble for a foul-mouthed tirade at referee Peter Walton.

The England ace appeared to shout ‘Ref, that was a pen, you f****** cheating c***', after being denied a penalty during Saturday's 1-1 draw at Reading.

Now disciplinary chiefs will write to the fiery Manchester United striker this week warning him to improve his behaviour.

The abusive outburst was clearly seen by viewers of BBC's Match of the Day.

But Walton ignored the comments and took no action.

A similar tirade from Rooney in February 2005 forced the FA to change their rules to deal with players who swear at officials.

Then he repeatedly shouted ‘F*** off' at referee Graham Poll during the 4-2 Premiership victory over Arsenal at Highbury, after earlier being booked.

They will not pursue the matter any further, though, and have made it clear no disciplinary action will follow.

That is probably just as well for FA bosses.

Rooney has already threatened to withdraw from all future sponsorship work with England, after the FA refused to overturn his recent suspension.
