How to avoid red mist and red cards: Be cold-blooded, says Arsene Wenger

Arsene Wenger is a fan of Diego Costa and has warned his defence they must be “cold-blooded” to deal with the Chelsea striker – who he says could do without the added theatrics which accompany his game.

Costa has proved a thorn in the side of Arsenal’s defence in recent times, including scoring the winner in the meeting between the two teams at the Emirates Stadium last season.

The London clubs renew their rivalry this evening with Arsenal looking for a first Premier League win over the Blues since October 2011.
