Southampton have signed Aston Villa's Republic of Ireland international left-back Stephen O'Halloran, 20, on an initial month's loan.

With Villa already out of the FA Cup, they have given Saints permission to field him in that competition.

"He is a young defender who can play on the left or at centre-back," boss George Burley told Saints' website.

"He will give us a bit more depth and a few more options - and it is good to bring a fresh face into the squad."
