Arsenal boss Unai Emery believes Alexandre Lacazette has another gear to his game.

Emery says the best is yet to come from a player currently being kept out of the French national side by Didier Deschamps' preference for ex-Arsenal striker Olivier Giroud.

Emery explained his approach for improving the player they affectionately call Laca and added: "We speak all the time.

"For him, last year, his first year in the Premier League was different to what he was used to in the French league.

"Also he had to adapt his position and the rhythm also, but not the mentality because he has a very good mentality. And when he has good chances he usually scores. He is very efficient.

"Now he needs to continue his adaptation for us, for the Premier League, for the rhythm.

"This season we are looking at him to take one step more in this level. We are very happy but my message to him is: 'Every day, don't stop'.

"Don't stop in training, don't stop in matches, carry on to find your best performance.

"And he has been doing that. I believe in him and in the other players."
