Alexandre Lacazette has warned Arsenal's rivals to be wary of a confident Nicolas Pepe.

The club's record signing was excellent in Sunday's 4-0 win over Newcastle United, scoring once and providing two assists.

And Lacazette believes there is plenty more to come from the former Lille man.

"I used to say we need to be patient with him," said the striker. "He is still young, he came from another league and it is always different.

"The Premier League is the hardest league in the world I think, so you have to be nice with new players like him.

"He is someone who needs confidence and when you give him confidence he is better. He just needs time to understand how the league is and now we can see a really good Nicolas Pepe."
