Sunderland's players need to shape up following their slow start to the season, says manager David Moyes.
David Moyes has called on his Sunderland players to prove they are good enough to cut it in the Premier League.
Moyes succeeded new England coach Sam Allardyce at the Stadium of Light in July but has endured a difficult transfer window and a slow start to the season during his first two months in charge.
The Wearsiders have taken just one point from their opening four games of the league campaign and suffered a demoralising 3-0 defeat at home to Moyes' former club Everton on Monday.
