Sir Alex Ferguson does not believe it was worth spending £25million to keep Carlos Tevez at Manchester United, but has backed Manchester City's pursuit of John Terry.
Tevez spent the previous two seasons on loan at United, but a permanent deal failed to be agreed and the Argentine striker has since joined local rivals City.
Ferguson reiterated the Premier League champions did make an offer to hang on to Tevez, but feels the price tag was too much for the 25-year-old.
"We made contact with Carlos, I sent him texts and spoke to him when he was in Argentina," said Ferguson.
"David Gill (United chief executive) made an offer to Kia Joorabchian, so I spoke to Carlos before the Inter Milan game (in the spring) and said that we had spoken to Kia.
Fans' hero"But we never heard back. In my opinion I didn't think he was worth £25million, that's just my judgment, maybe I'm wrong.
"The fans quite rightly have their heroes, and I respect the fans, so I was happy to go along with a deal as long as it was the right deal.
"Our success is down to the fans and their support, we need them when we are away from home to the likes of Fulham and Arsenal. But simply he was not worth £25m."
Tevez is just one of several big-name signings this summer for City, who are also determined to sign Chelsea captain Terry.
Ferguson understands why his City counterpart Mark Hughes is chasing the England skipper, claiming it is a 'sensible' move.
He added: "I think that's understandable, given the money they've got. They're not stopping. So, if I was in City's shoes, with all that kind of money, then I would have a go at that myself. I think it's sensible.
"He has experience and is the England captain. (Smiling) For some reason they must have known that he was interested. I'm sure there have been plenty of phone calls going on."
