Manchester United boss Sir Alex Ferguson has again slammed Chelsea over the Mark Clattenburg saga.

Ferguson yesterday welcomed the FA's decision not to charge referee Clattenburg, accused by Chelsea of making racist remarks to John Mikel Obi during their defeat by United this season.

"I didn't believe it anyway," he said. "Mark has had to carry this stain on his character for weeks and everybody in the game is pleased for him, apart from Chelsea."
