Manchester United's Sam Johnstone has joined Aston Villa on loan until the end of the season, while fellow goalkeeper Joel Pereira has returned to Old Trafford from his spell with Belenenses.
Johnstone, 23, is yet to make an appearance for United but has trained with the first team, been in matchday squads and is contracted to the club until 2018.
He is the first signing of the transfer window for Villa manager and former United captain Steve Bruce, who is hoping to get the Championship club promoted back to the Premier League this season.
"I'm really pleased to have joined Aston Villa, it's a massive club," Johnstone, who has been capped by England under-20s, told Villa's official website.
