West Ham attacker Tomas Soucek insists they're capable of upsetting Bayer Leverkusen tomorrow night.

West Ham host the second-leg of their Europa League quarterfinal trailing 2-0.

“We've done it before, so we have to be confident we can do it again," said Souček to whufc.com. “Against Sevilla, the atmosphere was the best I've ever heard and it was a night to remember. I scored the first goal and Andriy [Yarmolenko] scored the second. It was one of the best nights I have had here.

"We came home and knew it was going to be difficult, because they [Sevilla] were a good side and had won the Europa League three years in a row before that. It was quite tough, but together with the fans we got through it.

"We notice a difference to the fans on European nights, because in the warm-up we feel the atmosphere and that everyone is behind us. We know in European football that the fans are always behind us, even if we are losing.

“We went to the semi-finals, where we lost to [Eintracht] Frankfurt. We were so disappointed, but we bounced back and won the UEFA Europa Conference League, and then recently we had a great night against SC Freiburg. Hopefully, Thursday will be another special memory."
