Eden Hazard inspired Chelsea to a 2-0 win at Wigan on his Premier League debut, providing an assist for Branislav Ivanovic to score in the second minute before being fouled for Frank Lampard's penalty five minutes later.
Chelsea remained comfortable for the rest of the match, although Wigan midfielder Jordi Gomez missed several chances in the second half.
Chelsea manager Roberto Di Matteo was delighted with the Hazard's impact.
''Hazard was outstanding, produced a lot of quality and was always a threat,'' Di Matteo said. ''He was difficult to mark and it was pleasant to watch him today.
''It was perfect that we managed to score two early on. It settled nerves. We were looking for a good start, but it doesn't always happen.''
Wigan debutant Ivan Ramis was at fault for both Chelsea goals - Hazard turning away from him to play in Ivanovic and the Spanish defender brought down the Belgian international in the penalty area moments later.
Manager Roberto Martinez refused to criticize Ramis after the match, instead preferring to focus on his team's improved performance after going two goals down.
''We didn't start with the intensity you need in the league. It was like a preseason game, but I was pleased with the reaction,'' Martinez said. ''If you drop one percent in this league, you get punished. I felt we had our chances, and if we had scored at least once we would have a better feeling. It is a start we can build on though.''
Ramis made up for his error in the second half, clearing Fernando Torres' chip off the line as Chelsea looked to increase its lead. Brazilian attacking midfielder Oscar, who came off the bench to make his first Chelsea appearance, also went close in the finishing stages.
