Carlos Tevez completed his move to Manchester City on a five-year contract on Tuesday, and rubbished claims made by Sir Alex Ferguson that he had shunned calls from his former manager.
The Manchester United boss claimed he had attempted to contact Tevez on a number of occasions to persuade him to remain at Old Trafford, but was blanked. But Tevez has now claimed that is not true.
Tevez, who cost the club a fee in the region of £25m, said: "I was there for two years and Sir Alex never called or sent any text messages in that time.
"The only time he talked to me was after a match against Roma to discuss a situation about going to play for Argentina.
"It doesn't seem that this is the way to treat a player in two years at the club. it doesn't seem there is a line of communication.''
The 25-year-old did go on to thank United, adding: "David Gill (United chief executive), Alex Ferguson and the club's fan base I thank you for the time I spent there, but this is a new life for me and I am happy to be at Manchester City.''
Sir Alex also believed that Tevez had agreed to join City as long ago as January, something else the 25-year-old denies: "It is United people talking about signing a contract (in January) but it is not true that it was decided then.''
Meanwhile, Mark Hughes confirmed that City are still looking for further signings and that talks are on-going with Emmanuel Adebayor of Arsenal, and he is a firm admirer of Chelsea skipper John Terry.
Hughes said of his future summer transfer dealings: "There may well be opportunities that present themselves. There are areas of the team we still want to strengthen.
"We would like to obviously be in a position at the beginning of the season to have a team in place that we think can challenge this year.
"If opportunities present themselves we could possibly buy more players.
"I think there's been discussions between ourselves and Arsenal [for Adebayor] but, as is my usual response about players that we haven't signed, really it's not the right time or place to discuss that - only in as much as yes there has been contact.
"There's a deal to be done possibly but it's not been concluded as we speak. Until it actually happens, really it's not the time or the place to discuss it here.''
When asked about Terry, he replied: "I have fantastic respect for John Terry, ever since I saw him as a young player when I was at Chelsea as a player myself.
"He's a great player and an outstanding captain. But he's very much a Chelsea player at this moment in time.
"I have huge respect for him. I think any manager would covet a player of the type of John Terry, but at this moment in time he's a player for Chelsea so we have to respect that.''
When asked whether Tevez represents good value for money, Hughes said: "Absolutely, for Manchester City, it's absolutely good value.
"From our point of view, where we are in our development, to be able to bring one of the top strikers in world football to our club is a fantastic thing for us as a club, for our fans and everybody connected with Manchester City.
"We're absolutely delighted that Carlos is here.''
