"If we win the Europa League like this, I don't care which position I play
"If I have to help the team there, I have to help. I'm the guy who will do everything for the team.
"Of course, everyone knows it's not my regular position but with the team-mates, they help me and coach me as well, in front and behind.
"I'm so happy I helped the team in this position as well. I try my best and in the last two games it was a good performance."
We had a very good game
"The game plan that the boss gave us was excellent and we showed a big game. I think we deserved to go through after the two games.
"The character of the team was excellent. To win here 4-0 is not easy but like I said before, we showed over 90 minutes a great performance."
