Manchester City academy chief Jim Cassell says Chelsea have wasted the talent of winger Shaun Wright-Phillips.
"When he plays in the centre he has many ways to get past people.
"Shaun is a great guy and a terrific player. He was the first player to break through at City after we had put the academy structure in place.
"People say I did well for him, but I always tell them they're wrong. He did more for us than we ever did for him."
