Sarri reveals what Chelsea have been working on to stop Arsenal

Maurizio Sarri has warned Chelsea they cannot afford to switch off defensively against Arsenal.

Sarri’s side beat the Gunners in August and face them again today, this time at the Emirates Stadium.

And the Blues head coach revealed at a press conference ahead of the game that he has been working on dealing with Arsenal counter-attacking in wide areas.

He explained: “This match for us is a risk and it is an opportunity. It’s a risk of course because they are doing very well at home, so it’s a very difficult match and a very dangerous match for us.

“The match is very difficult because they are really a very good team. In the offensive phase I think they are one of the best teams in the Premier League. They are really very dangerous.

“In August it was a very different match. They changed in the last seven or eight matches.

“But we learned that they have really very dangerous movements in the offensive phase, especially when our full-back is out of the line to cover the ball.

“So we have to be careful. We have worked during this week on this. They are really very dangerous.”

Chelsea have struggled in front of goal at times this season but Sarri is confident they can cause Arsenal problems.

He said: “I think we can be dangerous against these opponents but we have to defend with a very high level of attention and application for 95 minutes.”
