Charlton tells Ronaldo to face down boo-boys

BOBBY Charlton has warned Cristiano Ronaldo he faces a barrage of abuse during the opening weeks of the new season.

Ronaldo returned to Manchester United training on Monday for the first time following a World Cup campaign which saw him identified as public enemy number one by England supporters for his involvement in Wayne Rooney’s dismissal during the quarter-final defeat to Portugal.

Alan Shearer and Frank Lampard lambasted Ronaldo for his card-waving antics, with even Rooney initially expressing “disappointment” at his team-mate before apparently making peace with the 21-year-old.
