London - Arsene Wenger gets another chance to finally beat his old nemesis and keep the Premier League title race alive for a little longer when Arsenal host leaders Chelsea on Sunday.
For all the Frenchman's achievements during his long reign in north London, he has never enjoyed a win against a side managed by Jose Mourinho.
Five draws and seven defeats, the last of which was an acrimonious 2-0 reverse at Stamford Bridge when Wenger became embroiled in a touchline spat with Mourinho, is a miserable record that Wenger is desperate to improve.
