Man United goalkeeper Sam Johnstone seals loan to Aston Villa

Manchester United goalkeeper Sam Johnstone has joined Aston Villa on a season-long loan.

Johnstone, 24, returns to Villa having made 22 appearances for the Championship club following an initial loan switch from United in January.

"I am delighted to be back," former England Under-20 international Johnstone told the official Villa website. "I really enjoyed my last spell here -- it's a great club with top players and passionate fans.

"I can't wait to get started now. I believe it can be a special season for all of us and I will be working hard each and every day to produce the kind of performances that will help us achieve what we're aiming for."

Johnstone is yet to make a first team appearance for United but has played more than 100 senior games during spells at Scunthorpe, Walsall, Yeovil, Doncaster, Preston and Villa.

The England youth international has a year left on his contract after signing an extension in October.

Jose Mourinho took David De Gea, Sergio Romero and Joel Pereira to the United States for games against LA Galaxy, Real Salt Lake, Manchester City, Real Madrid and Barcelona.

United also have youngsters Dean Henderson, who has played for England's Under-20s, and Kieran O'Hara, who has represented Republic of Ireland Under-21s, on their books.
