Manchester United have officially signed Uruguayan defender Guillermo Varela for an undisclosed fee, making him David Moyes' first signing for the club since he replaced Sir Alex Ferguson.

"Manchester United is pleased to announce it has reached agreement to sign 20-year-old defender Guillermo Varela from Uruguayan club Club Atletico Penarol for an undisclosed fee," said a statement by Manchester United.

Manchester United is on the verge of signing Argentine defender Ezequiel Garay for a reported fee of £17 million if rumours are to be believed.

It was reported that Garay, who moved to Benfica from Real Madrid, would return to Santiago Bernabeu but Manchester United's new coach David Moyes seems to have convinced him to sign for the club.

It is also reported that Moyes is keen to bring back Cristiano Ronaldo who left for Spanish giants Real Madrid four years ago.

Manchester United are prepared to offer £65million plus a player to land Ronaldo, 28, who is still a hero with the United faithful, according to a report by The Sun.

The Red Devils' attacking line-up will be strengthened if they sign Ronaldo even if England star Wayne Rooney leaves the club as rumoured.

It is reported that Rooney, 27, who has been sidelined ever since Robin van Persie joined Manchester United, has reportedly placed a transfer request to Sir Alex Ferguson. He could well leave Old Trafford after nine years if the new coach David Moyes fails to convince him in the coming weeks.

Several clubs like Arsenal, Chelsea, Paris Saint-Germain and Bayern Munich have reportedly shown interest in signing the England striker if Manchester United give green signal for his exit.
