However, he insists such achievements occur in cycles.
After their Europa League win over Rennes, Emery said: "I knew in the Champions League and the Europa League, in different moments it is sometimes Spanish clubs, other times English clubs or Italian or German clubs. But it is one thing. Champions League is very important but the Europa League grew up a lot and now is giving every team the possibility to play in the Champions League. In the domestic league, like here, we have six teams playing to be in the top four.
"Two teams are going out and the Europa League is giving us a big opportunity also to take one way to go to the Champions League. And also, it's one title. I said to the players today, I am excited about this competition. It's not just because you can get to the Champions League through this competition. It's also because it's one title and I think we can feel the possibility to win one title, doing this way with a difficult moment like today and playing also against big teams.
"But I think we can feel this competition like in the Premier League, to do a good way and create, with our supporters, a big atmosphere and a big feeling together to do this way in the Premier League and also here in the Europa League. Together and stronger."
