Chelsea came from behind to beat Sunderland 3-1 and make it two wins from two in the English Premier football League.
Second-half goals from Michael Ballack, Frank Lampard and Deco cancelled out Darren Bent's 18th-minute strike for hosts Sunderland in a match dominated by the visitors.
Elsewhere, promoted Wolverhampton Wanderers held on at Wigan Athletic for their first victory of the season, winning 1-nil courtesy of a sixth-minute strike from Andrew Keogh.
