Still reeling from the departure of striker Asamoah Gyan to the United Arab Emirates, Bruce and the Black Cats fans were handed further reasons to be miserable as John Terry and Daniel Sturridge scored to leave Sunderland winless and wondering where their goals will come from.
Summer signing Ji-Dong Won scored his first goal in English football late on but it was too late as Chelsea held to keep up their unbeaten start under new boss Andre Villas-Boas.
He must have been pleased with the contribution of Mata as the Spaniard’s influence steadily grew throughout the game and he is certainly the creative link-up player the Portuguese coach worked so hard to find.
It was his free kick that lead to the opening goal after the hosts failed to clear the ball which hit the outside of the post allowing Terry to cooly side foot home.
Debutant Nicklas Bendtner huffed and puffed up front for the home side and headed an effort over in the first half whilst Stephane Sessegnon saw a strike pushed away by Peter Cech.
Where Sunderland failed in front of goal Sturridge succeeded as he wrapped up the points six minutes after the second half began. Deadline day signing released the striker who raced through on goal and audaciously back heeled the ball past Simon Mignolet.
The game petered out after that and with Dong slotting in Sunderland’s consolation a minute into injury time to give the home fans something to cheer.
