Manchester United have made their first signing of the summer after confirming the a deal for Antonio Valencia. The 23-year-old Ecuador international has signed a four-year contract, having moved for an undisclosed fee.

Valencia, who joins from Wigan Athletic where he scored three goals last season, is expected to help fill the void left by Cristiano Ronaldo following the Portuguese winger's £80million move to Real Madrid. Valencia is reported to have cost United in the region of £16million.

"Joining Manchester United is a dream come true for me," he said. "I have enjoyed my time at Wigan, but I am thrilled to have the chance to challenge for the biggest honours in club football here.

"Playing in front of 76,000 fans alongside players like Wayne Rooney, Rio Ferdinand and Ryan Giggs will be an amazing experience. I can't wait to get started."

Sir Alex Ferguson, the United manager, admitted he had tracked Valencia since he joined Wigan two seasons ago. "Antonio is a player we have admired for some time," he said. "I am sure his pace and ability will make a significant contribution to the team."
