Sunderland must cut out mistakes, says boss Gus Poyet

Sunderland manager Gus Poyet says his side must learn to avoid mistakes if they are to have any hope of winnings games away from home.

The Black Cats travel to 12th-placed Aston Villa on Saturday looking for their first away win of the season, and Poyet says his side need to find a balance between being competitive and keeping 11 men on the pitch.

A spate of defensive errors and red cards have cost Sunderland dear in recent matches away from home, leaving them bottom of the Premier League table.
