Actually, for the sake of fairness, it is worth recalling that Barcelona scored two goals in the time added by the referee. And so, if you take the pre-match layouts and if you don't watch the matches themselves, then yes, you can call Eintracht's victory and reaching the semifinals a big surprise. For me personally, when I watched the first match performed by these rivals, I immediately thought that Eintracht has certain chances of winning the final and therefore it did not come as a big shock to me. The only thing that came as a definite shock was how the second leg itself was shaping up and the three-goal advantage that was formed at a certain point in time. As for Frankfurt and West Ham, I would not rush with forecasts, Eintracht is too unpredictable this season.

Rangers are the only team that is a tough competitor in the title race in the local league, although this season they are not looking so good but Rangers are the second best team in the local league. But indeed, the chances here in the Europa League are not so good, because the quality of their local league is different and it is clear that teams from the Bundesliga have a better chance of qualifying for the final. But I personally can't say that Leipzig is a strong candidate for the team that won the Europa League title this season, because there is still West Ham there who seems to be a strong opponent. Is it possible that this season's final will be a Bundesliga team match for Eintracht Frankfurt v Leipzig, I think it is possible but still the two teams in the final will have the same chance of winning.

To be honest for me it doesn't matter how much preparation the opponent took for a while they have played in the match, Barcelona losing that match is going to be always a  shock for me. they really should not have lost that match. 

I know that he would look at the differences personally and it is a little self-explanatory why they have lost that match. but anywhere I think Xavi has done quite well with his team and did really well too to make the team reach his spot.

Obviously, the two teams in the finals are going to have the same chances of winning. that is why they are in the finals. Now I expect RB Leipzig to win the match. they should be the team to advance.

But to be honest, for me the interest in Europe League is just lessened a little bit because Barcelona is not there anymore and if they were playing in the Europa league till now it would have been a lot more interesting.

It's not about how the team plays and what is the probability that it will win the title. It's a matter of mathematics - if you look at it from the point of view of betting, then the chances of winning the title are equal to the chances of winning the semi-finals multiplied by the chances of winning the final. But in this case, it turns out that West Ham will beat Leipzig with a higher probability than Frankfurt, that is, it turns out that Frankfurt is quoted higher than Leipzig (but this is not true since we saw the quotes for the title).

Well this season Europe league is on another level and mostly really hard teams are in it and everyone wants to win it or go really far in it.
Also the reward with the champions league spot plus additional cash is really good so this is why most of the teams chase the title in this tournament. It will get even better with years to come.

Of course there is a big difference between the leagues these teams take place in so it doesn't matter much which one is in the league, because the teams that win all the matches against the simple teams can be very unsuccessful in the European matches (: West Ham are also one of the strongest candidates at the moment and I think we will watch in the final game, they can win their game against Frankfurt. We will watch a good final match

West Ham United are in good form in the last few matches in their domestic league while Frankfurt are certainly now with high confidence after they were able to beat Barcelona and advance to this semifinal.
I think the match between these two teams will be very balanced and interesting and both teams have the same chance to advance to the final round of the Europa League this season.

I agree with you. This match will definitely be balanced and competitive. The Frankfurt players are still very confident after the win over Barcelona. On the other hand, West Ham's performance in the Premier League is not bad. They are seventh in the table. So both teams will have to try to qualify for the finals. Moreover, West Ham's forward is good enough.
