Chelsea midfielder Pedro is confident Kepa Arrizabalaga will improve week by week.

Kepa conceded twice in yesterday's 3-2 victory over Arsenal.

But Pedro told chelseafc.com: "I think he's very young but with experience as well.

"He's played a lot of games in Spain with Athletic Bilbao and also played for the national team. He's very clever and very good in the air, he's fast when trying to save the ball and for this reason he's a good option for the team and he makes us stronger.

"It's very different [in England], I know that and I've spoken with him. For example, from corners it's very difficult to defend them with the central defenders and strikers but he knows this and he's seen in training the fast rhythm of the game. But joining Chelsea is a good choice for him and his career and it will help his grow as a player."
