West Brom boss Tony Pulis has told David Moyes he must adapt to Sunderland's relegation battle.
Albion go to the Stadium of Light on Saturday hoping to increase the misery on the new Black Cats manager after his winless start.
Sunderland are bottom of the Premier League with one point from their first six games since Moyes was appointed as Sam Allardyce's replacement in the summer.
Pulis has backed Moyes to get it right in the north east but believes, after his time at Manchester United and Everton, the Scot needs to rework his style to survive.
