LONDON (AFP) - Kurt Zouma and Eden Hazard scored as Chelsea exploited the dismissals of Gabriel and Santi Cazorla to beat Arsenal 2-0 on Saturday and revive their Premier League title defence.

Gabriel was sent off late in the first half after a tussle with the provocative Diego Costa and Zouma, playing in place of Chelsea captain John Terry, put the hosts ahead in the 53rd minute.

Cazorla was shown a second yellow card for sliding in on Cesc Fabregas and Hazard made the game safe a minute from time with a shot that beat former Chelsea goalkeeper Petr Cech via a deflection off Calum Chambers.

It was a first home league win of the campaign for Chelsea and, arriving on the back of Wednesday's 4-0 win over Maccabi Tel Aviv in the Champions League, fired hope that Jose Mourinho's side may yet salvage something despite making their worst start to a season in 29 years.

Arsenal manager Arsene Wenger had overcome Mourinho for the first time in last month's Community Shield, but here found himself in the familiar position of having been eclipsed by his Portuguese nemesis.

His side have not beaten Chelsea in the league since October 2011 and following the mid-week Champions League defeat by Dinamo Zagreb in which Olivier Giroud was sent off, this was another partly self-inflicted setback.

As ever in this fixture, the first tremors of the contest were felt before kick-off, with Terry's inclusion on the substitutes' bench followed by a keenly anticipated handshake between Wenger and Mourinho.

Wenger had swerved a chance to shake his Chelsea counterpart's hand after Arsenal's 1-0 win in the Community Shield, but on this occasion Mourinho made himself impossible to avoid by lingering beside the tunnel. Eyes averted, the pair performed the most perfunctory of handshakes before taking their seats.
