Paolo Di Canio's stint in charge of Sunderland almost got off to a positive start when Stephane Sessegnon had a chance with three minutes played. However, the attacker could only find the side-netting from a narrow angle.

Goalscoring chances were few and far between during the remainder of the half, with both defences on top.
Just when it looked as though the sides were going to go into the break level, struggling Sunderland found the net.
John O'Shea flicked the ball on at the near post and the ball was diverted in via Chelsea defender Azpilicueta.
