Chelsea captain Cesar Azpilicueta paid tribute to Kepa Arrizabalaga after their FA Cup win against Plymouth Argyle.

Kepa saved an extra-time penalty to secure the 2-1 win.

"Kepa is brilliant," said Azpilicueta

"He is a great example to everybody. He has gone through a lot of difficulties at this club, but he has always had a positive attitude.

"He looks at himself, improves for the team, even if it's not easy to be number two. He always supports Edou. We have a fantastic group of goalkeepers, Edou, Kepa, Marcus, with Hilario the goalkeeping coach. Whoever plays is ready and we saw that again."

On the performance, Azpilicueta continued: "When you have the ball in the final third, you need to create movement. Sometimes the attacking guys need a bit of support from the back, sometimes unselfish runs to create space for our team-mates, but overall we need to be more aggressive and occupy the box better.

"We are happy to go through, but we know there are a lot of things to improve, and we will work on them straightaway."
