Arsenal boss Unai Emery has praised Maurizio Sarri for his work with Chelsea this season.

The two managers face-off tomorrow.

Emery said, "I think his team has one very good idea and a very good personality, which is what we wants, how he played with Napoli. Now, when you watch Chelsea's matches, they are playing well and they are playing with this identity.

"For us also, it's a good test and we hope we can impose ourselves. Usually, they will impose themselves on the opposition in each of their matches, and they also won against Manchester City. I think this test is the same for us. If we can impose our idea, our game plan, against them, it's the best test for us."
