Sunderland 0-0 Crystal Palace: Tony Pulis prepared for 'tough' relegation battle

Crystal Palace manager Tony Pulis says the Premier League relegation battle is the "toughest it's been for a long time", as his side draw 0-0 against fellow strugglers Sunderland.

Kagisho Dikgacoi had Palace's best chance, firing an effort wide late on, but the points were shared at the Stadium of Light.

Palace remain three points clear of the drop zone, just above Sunderland.
