Amorim admits the atmosphere he felt was very different compared to previous games.
He said after the 4-2 win, "I think, after the third goal, the noise of the stadium was not normal. It was like a different moment. It was the first time that I felt that sound within the environment.
"So it was a very good moment for me. So, of course, we are focusing on the game but there are something things in this club, in this stadium, that you feel. And that was really strange. The sound of the stadium was incredible.
"Even when we arrived to play this game, I felt that the environment with everything, with everybody here, the players, was different.
"It was not like being overwhelmed, it was excitement to come here to play in front of our fans and that was a different feeling. The confidence is normal because it comes with wins."
