"Playing a derby as important as that one was a different feeling," he told Lancenet. "I am very happy to have achieved that beautiful win and to have advanced to the next round.

"I am happy with myself, as I think I am improving every match."I ran a lot, I managed to create some good plays and help the team.

"I'm feeling physically better and slowly becoming more confident. I am sure I'll grow even more, improve with every game. What is important is that I am happy and that I am earning my place."
