Black Cats pair back in action

Sunderland are strengthened by the return from injury of full-back Stephen Wright (knee ligament) and Christian Bassila (hamstring) for a crucial relegation clash with Aston Villa at the Stadium of Light.

Wright has been out since the opening day of the season while former Strasbourg captain Bassila has missed the last five matches. Julio Arca (foot) will not be risked despite returning to training.
