Sam Allardyce: Sunderland boss pleased with clean sheet

Sunderland manager Sam Allardyce says "it is no coincidence" his side have kept a clean sheet in both their Premier League victories this season, after a 1-0 victory at Crystal Palace.

In the 80th minute, striker Jermain Defoe nicked the ball from the indecisive Scott Dann and poked in the only goal.

Defoe has now hit seven goals in nine starts for Sunderland in all competitions this season.
