Ahead of the clash between top two sides in the league, Chelsea and Arsenal, midfielder Francis Coquelin feels he will need to be focused for 90 minutes if they want to stop the Blues.

The Gunners host Chelsea at the Emirates Stadium on Sunday and if the north Londoners want to cut the deficit from 10 points to seven, Coquelin knows he will have to do a tight job on Blues ace Eden Hazard.

He told Arsenal Player: "We've played against big teams in the last few weeks.

"Liverpool have Philippe Coutinho and now it's going to be different opposition with Eden Hazard. He is probably one of the best players in the league, maybe even the best this season. It's going to be a tough game but like in every big game you want to win.

"Hazard and Cesc Fabregas are great players who can do such great things at any time in the day. You need to be focused the whole time and that's what I'm trying to do for the 90 minutes."

Coquelin was recalled from a short loan at Charlton Athletic back in December and since then has played a significant role in the resurgence of the Gunners who have won eight Premier League matches on the trot.
