I'm happy to be back in the team and also to get a win in the derby," he said post-game.
It's a really important game, so I'm very happy. Everything depends on us. We have to continue winning our games, we have a few more games left and we have to win them all.
It was a very good game, we went all out from the beginning because we knew how important this game was. If we don't approach it right we are not able to win, but we did everything right and I'm really proud of the squad."
