Chelsea defender Cesar Azpilicueta admits he's a very different player to the one who arrived from Marseille.

The Spaniard has just reached 150 games for the club.

"When you arrive at a big club it's a challenge: to adapt to a new league, a new language, everything. I was adapting step by step and I was very pleased to come here. My goal was just to keep improving," he told chelseafc.com.

"I have changed quite a lot since then," he adds. "I have had the chance to work with the best manager and with the best players. The club have all the facilities to help you improve. I have played on the left side, too. It's my fourth season here and I have improved. Now I want to keep growing with the club and with the team, and to keep developing as a player."
