Manchester United signs Victor Valdes as De Gea Backup

 Former Barcelona goalkeeper Victor Valdes has signed for Manchester United as "the number two goalkeeper", said manager Louis van Gaal.

The 32-year-old Spain international has penned an 18-month deal, with the option of another year.

Valdes had been training with United as he recovered from a serious knee injury after his Barca contract expired.

"I can already see this is a very special club," said Valdes, who will deputise for David De Gea.

"I worked with Louis van Gaal during my time at Barcelona and to have the opportunity to work with him here at Manchester United is a dream come true."

Van Gaal said that Valdes had been "very impressive" during training.

"He joins the club as the number two goalkeeper and is a great addition to the first team," the Dutchman added.
