Even with a recovering Frank Lampard, Chelsea looks potent heading into the English Premier League season.
Lampard and Romelu Lukaku scored in the second half to lead Chelsea to a 2-1 victory over Roma in the final friendly of its pre-season American tour before its Aug. 18 opener at Hull City.
Lampard, who has been recovering from an Achilles injury this summer, scored on a 20-yard strike inside the left post to level the score in the 61st minute after Eric Lamela's opportunistic 21st minute goal put Roma ahead.
"I find it hard to put a percentage on it," Lampard, the club's all-time leading scorer, said of his fitness.
"I feel good. We've had a good, strong preseason now, lots of games, lots of training. I think we're ready. We'll be ready next week."
The Blues won all three of their friendlies against Italian clubs in the United States, defeating Inter Milan and AC Milan earlier this month before falling 3-1 to Real Madrid on Wednesday.
Lampard sat out the first two matches before playing the first half against Real Madrid.
Chelsea created more chances throughout Saturday's match and was rewarded in the closing moments when Hazard rounded the Roma defense on the left side and drove a shot into goalkeeper Morgan de Sanctis' body.
The rebound fell to Demba Ba, who found Lukaku in front of the net for the game-winner.
Roma, playing its last friendly of a three-match North American tour, had previously defeated the Major League Soccer All-Stars and the MLS club Toronto FC. The club opens its Serie A season at Livorno on Aug. 25.
