Atletico Madrid striker Diego Forlan admits regrets over his time at Manchester United.
Of his time at Old Trafford, Forlan believes he could have struck up a good partnership with Wayne Rooney whose arrival coincided with his departure.
"I was very young at Manchester United and I feel that I was just starting to find my feet when I was sold and Rooney was brought in.
"If we had been paired together I think we could have formed the most devastating strike partnership in Europe but it wasn't to be," he said.
