Wigan's Victor Moses tested Czech twice
Samir Nasri saved Manchester City's blushes as the Frenchman scored a late winner to beat a battling Southampton in a dramatic game at the Etihad.
Having lost Sergio Aguero to injury and with David Silva missing a penalty, Carlos Tevez opened the scoring by shooting low past Kelvin Davis.
Southampton took an incredible lead when substitutes Rickie Lambert and Steven Davis scored after the break, reports the BBC.
Edin Dzeko equalised following a corner and Nasri won it with 10 minutes left.
It was an amazing start to the season for Premier League champions Manchester City in keeping with their final game last term, when they sealed the title in stoppage time against QPR by the same scoreline.
That day, Aguero was the saviour but other than letting the lead slip to Nigel Adkins' side, his knee injury will cause City huge concern after he was stretchered off early on in the game.
Meanwhile, Eden Hazard made an impressive Premier League debut for Chelsea as they held off a tenacious Wigan side to win 2-0.
The Belgian midfielder turned neatly before sending Branislav Ivanovic clear to sidefoot in the first.
Hazard was then felled for the penalty which allowed Frank Lampard to double Chelsea's lead after just six minutes.
But Wigan's Victor Moses twice tested Chelsea keeper Petr Cech while Jordi Gomez headed one chance off target before screwing a volley wide late on.
