Arsenal legend Paul Merson has identified a Chelsea player who could pose a threat to his high flying former side.

The Gunners are second in the Premier League, only behind rivals Tottenham on goal difference.

Merson believes that while they are favourites to beat Chelsea after the international break, they will have to watch out for Raheem Sterling.

"They will have a go at Chelsea, so it will be interesting," said Merson in his Sky Sports column.

"But against the better teams, like Liverpool who had a right go, those are the games they have played well in this season.

"So it will be interesting but, where Chelsea are in the league, teams will not want to play them as, on their day, they can beat anybody and when Raheem Sterling is playing like he did at Burnley, then he is unplayable."
