West Ham boss David Moyes was proud of his players after their 3-0 win at Lyon.
The result sees West Ham reach the Europa League semifinal 4-1 on aggregate.
Moyes said: "Immensely proud of the players and the performance and probably more so, when you look back, of the performance in the second-half of the first leg when we were down to 10 men, which looked a really poor decision. The players stuck at it, never gave up, got a goal in front before we conceded. I don't think anyone, when they were putting questions to me earlier, thought we were going to make it tonight.
"If you have a good team spirit... all managers would like to get that and it is not easy. t mainly comes from winning. Good results builds it. We have a great group of lads. I'm lucky. They have been great in the time I have been here. And the journey in two years from trying to avoid relegation and now we are talking about getting to the semi-final of a major European tournament. It is fabulous and we are all going to look forward to it.
"It is huge what we have done in two years. We have not won any trophies yet but we are trying to compete and to qualify from European football again, if we can. To be getting to these later stages, we have beaten big clubs that are used to European football. You don't win anything for tonight but it was a big moment for us. Winning 3-0 away from home in Europe - really good result.
"When we were qualifying last year and you could hear all the West Ham supporters shouting 'we are going on a European tour'. They've had a pretty good tour this year - Belgium, Croatia, France tonight. We've been to Spain. I'm sure they'll all be looking forward to going to Germany as well."
