Atletico Madrid goalkeeper David de Gea was undergoing a medical at Manchester United on Monday afternoon.
De Gea, 20, has long been expected to complete a move to Old Trafford and, following the conclusion of his successful European Under-21 Championship campaign with Spain, he is now due to complete the switch, which will reportedly cost £17.8 million.
Liverpool goalkeeper Pepe Reina had told La Gaceta: "I very much welcome this news because David is a great keeper. When it becomes official he is going to start working to prove in the Premier League what a good goalkeeper he is."
De Gea arrives to replace Edwin van der Sar, who retired at the end of the season after a six-year spell at Old Trafford in which he won four Premier League titles, the Champions League and League Cup.
