"Only Diego is injured, everybody else is fine and ready (to play at QPR). I think we have eight matches to play, if he plays four it is normal. If he plays three he is a bit below what I am expecting. If he plays five that is more than I am expecting. I am not concerned (by his injury)."

Another defining BBC voice, football's John Motson, has had this to say about fellow commentary great Richie Benaud on BBC Radio 5 Live...

"He will always be remembered for the clipped phrase and economy of words. I met him once and he told me when he finished playing Test cricket he trained on a course to be a commentator at the BBC. That is the kind of determination he had.

"He was part of a group that styled commentary on the BBC from the 1960s onwards. When that cricket tune played on BBC One you knew you would hear that perfect voice of Benaud telling you what was happening in a perfectly economic fashion.

"Having being an Australian captain he spoke with so much authority and gave such superb insight into the game. He had the ability to put his finger on the key moment that defined it - he had a great gift for that."
