European competitions are different so we can't predict the results with accuracy. The intensity of the game between Frankfurt and Barcelona is very interesting because Frankfurt appear impressive both in attack and defense although basically Barcelona's dominance in this match is also good.
Frankfurt recorded quite a lot of kicks throughout the match despite only managing to score 1 goal. They performed as the coach expected "to defend well and take chances when they got the ball on the counter-attack". There were 5 counter attacks by Frankfurt throughout the match compared to 0 by Barcelona, ​​so Frankfurt deserved a draw in that match. But I was amazed by Barcelona's performance in that match where they can still maintain an unbeaten record so far.

Leipzig's current form is very good and after winning their German League match against Dortmund with score of 1 - 4 mostly peoples were feeling they can beat Atlanta which is struggling badly in last few matches, but they have done good come back in this match and now any result is possible in second leg match as both teams have fair chance for qualifying into semi-final with most chances we will have German Leipzig into next round because Atlanta is having some poor run at home against their Italian sides so here Leipzig can take some good advantage and go though. But, good thing we have all quality performance from all eight sides in these matches which will bring some good entertainment in second leg as well.

As far as I know West Ham only play well at home while their away game is pretty bad I doubt they can beat Lyon who has a strong defense
Losing one of the defenders can weaken their defense too Lyon can take advantage there in addition to the advantage of playing at home
West Ham don't have much experience in the Europa League hard to imagine they can go to the next stage.

Frankfurt really put up a fight against Barcelona, they made it difficult for Barcelona to score. They could even keep the score after one of their players was shown a red card and had to play 10 men. It was beyond my expectation that Barcelona would win the match, even though they didn't lose but Frankfurt gave Barcelona a surprise.

I did not expected this many draws, it was seriously closer than I imagined. I imagined Leipzig would win, Barcelona would win and interestingly West Ham would win as well looking how they are doing better in a better league. Braga wasn't expected neither and was the only game I would say a draw, and if not then rangers to win as well.

I have to say this weeks of europa games made me lose a lot and I wasn't even close in some of them. Like Barcelona looked like a fairly easy bet, and I wagered 2.5+ goals on Barcelona . Let alone a draw, I expected them to beat by that many. Interesting to see that they had trouble all over again, they are great at league but europa seems to be a difficult for them.

This matchday is strange, the quarterfinals with 4 games and 3 end 1-1 and the 4th 1-0. As if all teams have the same tactics in the first game and only at Glasgow Rangers did it not work. The favorite to win the Europa League is FC Barcelona, i hope that a German team plays in the final.

I don't think Barcelona is going to lose the second leg because the score in the first leg was 1-1.

So obviously, neither team has any benefit over the other. You know, the second leg is going to be played in Camp Nou, and obviously, Barcelona should have the advantage in home conditions.

Now what I am wondering is what if Barcelona does not win the second leg and doesn't at once in the Europa league?

Is that good compared to where Barcelona was at the start of the season or is that bad because Barcelona was in the form before this match?

I personally don't see it as something strange because for me, it's normal in some matches they get the same result. After all it's a tight tournament that even, in the first leg in the previous round of 16, we were surprised by Galatasaray who can hold Barcelona to a draw and now the team from Germany can do that too and I think that's normal. Also, regarding the other matches I think they are all opponents that have at least equal quality, like Leipzig v Atalanta, West Ham v Lyon. If it's about Braga v Rangers it's also a reasonable result, considering that the Portuguese team can sometimes only score a few goals and are able to defend quite strong.

Barcelona that struggled to get a draw against Frankfurt is the team you are considering to win the competition, probably we all are looking at the name of the clubs to determine who might win, personally I will give it to Atlanta, they have what it takes to win this competition, don't be if Frankfurt pull a suprise win at Nou camp, despite a man down they still managed to get a draw, if this Barcelona squad have a man down in the second leg I doubt if they will qualify for next round
