Arsenal goalkeeper Petr Cech was delighted with his cleansheet for their 1-0 win at Europa League opponents Napoli.

Alexandre Lacazette struck a superb free-kick to send the Gunners into the semifinals 3-0 on aggregate.

Cech remarked: "It was a very difficult game but we made it look easier because we played really well. We controlled the game really well and we defended really well too. We scored the goal which was very important for us and it gave us a big advantage after the first leg. Then we defended really well and created some good opportunities going forward, so we could have scored a second goal.

"Napoli are a fantastic team who always score a lot of goals, especially here at home, so to keep two clean sheets is obviously something [positive]. We've done really well and we can be happy with our defensive organisation.

"Today is a perfect example that when you play as a team and you're ready and help each other, you will be fine."
