The Spaniard capped a powerful start for the Blues by firing them into an 11th-minute lead - scoring his first league goal since October 6 - and he made it 2-0 in first-half stoppage time by converting a penalty awarded for Sebastian Larsson's trip on Ramires.
Only the woodwork prevented him from completing a hat-trick inside 49 minutes, but Juan Mata rifled in the loose ball to end the game as a contest. Adam Johnson scored Sunderland's consolation in the 66th minute.
