West Ham boss David Moyes is delighted reaching the Europa Conference League semifinals.
A 4-1 victory over KAA Gent sees West Ham reach the final four 5-2 on aggregate.
Moyes said: "Look, I felt a big relief because we hadn't played well in the first game against them, and losing a goal in the first half was terrible and I was thinking, my goodness, this is maybe going against us tonight.
"But we were the better team, even in the first half I thought. We got back in the game and then we missed two brilliant chances to go ahead before we got the penalty kick.
"It was a big relief when we got the third goal because it put complete daylight between us and the thought of getting to a European semi-final two years in a row with West Ham was special.
"Once you start to get [European success] in your blood it's what you want.
"You want these big nights, you want to get used to it. Great credit to the players, it really is for them to do this.
"We've got a lot of new players this year too, but we won the group last year, we won the group this year as well. We got through big games last year and now we've got through another couple of big games and we've got to a semi-final.
"You know what I'm going to say though we've got to go one stage further this time, so I hope the experience we had for the game last year, the way the game went, we can maybe try to use that.
"Maybe we're running into a little bit more form. We scored four tonight and I thought we could probably have scored seven if we had been really clinical.
"Overall, I'm thrilled with how the players have done it, and on the back of a good result at the weekend hopefully it keeps our confidence up."
