Manchester City have officially completed the signing of forward Carlos Tevez and have approched Arsenal about the availability of striker Emmanuel Adebayor. The Argentinean has signed what is thought to be a five-year deal after passing a medical to become the latest in a line of high-profile acquisitions by the wealthy Eastlands club.

Speculation suggests the Argentina international could yet be joined by Chelsea captain John Terry, while Mark Hughes admitted this afternoon that City have been in contact with Arsenal about a move for their Togo striker.

Tevez was presented to the media today a day ahead of the Blues’ three-match tour of South Africa, which they depart for tomorrow and, though he claimed Alex Ferguson did not communicate with him during his time at Manchester United, he thanked the Scot, the club and the fans after spending two years on loan at Old Trafford.

Speaking through an interpreter, Tevez 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."

Tevez also denied that he had spoken to City's representatives about a transfer in January.

"It is United people talking about signing a contract (in January) but it is not true that it was decided then," he said.

City manager Mark Hughes indicated Tevez may not be the last big-name arrival at Eastlands this summer.

"There may well be opportunities that present themselves," he said. "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."

When asked whether Tevez represents good value for money, Hughes replied: "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."

Hughes then confirmed contact with the Gunners.

"I think there's been discussions between ourselves and Arsenal 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 if a deal for Terry could be resurrected, 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."
