Barcelona got lucky because they will play against a team that is not very strong so this must be a very easy game for barcelona to win

Atalanta found a strong team so I won't be surprised if they lose

Braga also found a strong team, I doubt that Braga can win

west ham was also unlucky to find a strong team, i also doubt that west ham can win

Barcelona will face Frankfurt which isn't a top team nor playing extra right now. Just a casual team that could be passed relatively easily if they play as usual.
Barcelona also will get ride from one of Leipzig or Atalanta which are favourites for the title. That draw was in their favour imo.

Don't forget that the Frankfurt team has been able to qualify for this round after beating a team like Real Betis. Although their performance in the league is weak, maybe they will continue their best efforts to do well in the Europa League. Barcelona is strong, but it is foolish to think that they will win easily.
The match between Leipzig and Atlanta will be very interesting. Both teams are very strong. They will also want to win the Europa League title. We will see one of these two teams in the final.

Frankfurt have doing well so far until qualify on quarter final but I think not enough stronger for Barcelona exactly Aubameyang have good and top performance trough against with Frankfurt during with Dortmund until Arsenal and always scoring goal. I see potential for Barcelona continue to semi final on UEFA Europa League and have chance get first trophy for Xavi Hernandez if keep consistent for 1st and 2nd leg against with Frankfurt. So far as the UEFA Europa League chance for Barcelona to get trophy after have out on Copa del Rey and La Liga title race have close by Real Madrid.

Of the several teams remaining in the Europa League this season I think the quality that Barcelona has above all of these teams, so it is very likely that Barcelona can win the Europa League this season if they are able to be consistent with their current game.
Xavi's arrival to coach Barcelona seemed very clearly capable of changing everything and the arrival of several new players made a very positive contribution, now Barcelona are very productive in scoring goals, all of which cannot be separated from the arrival of some of their new strikers such as Aubameyang and Adama Traore.
considering the La Liga title is already impossible for Barcelona to get because they are far behind Real Madrid at the top of the table, of course Barcelona put all their focus on the Europa League and that way I am very confident with the quality of the players they have they will be able to win it.

I also agree with that and I think they could really be a favourite. Frankfurt is actually not an easy opponent for Barcelona and they may still trouble Barcelona in the quarter-finals, but a good performance from Barcelona so far can convince me that they can beat Frankfurt in two legs.

For obvious reasons I really think Barcelona can reach the final of the Europa League this season although they should really do it without any mistakes. Aubameyang has scored his second goal for the Europa League and he can really be relied on now. The whole team seems pretty excited, but I'd really like to see them do the same in the upcoming El Clasico.

I hope that if barcelona can meet westham or atlanta, but unfortunately they actually benefit by facing frankfurt which is clearly a weak opponent, in my opinion against frankfurk is not a difficult match for barcelona later, especially when compared to barcelona, ​​frankfurt has a pretty bad performance currently in the league, so I think it's very possible that barcelona will be able to easily advance to the final if we look at the teams that are left at the moment.

It seems to me that Xavi has brought stability to the club. There is no more talk about the finances of the club, the departure of Messi, or the coach.
The players are completely focused on the game and the team and that can be seen in the results.
Unfortunately, it is too late for Barcelona to get involved in the fight for the Spanish title this season, they also dropped out of the Champions League and I think Xavi will try to win this competition, the only competition where there is still a chance for this season's trophy for Barcelona.
I think Barcelona's chances of winning this competition are very good and their main competitors are West Ham, Leipzig and Rangers.

Looks like you underestimated Eintracht Frankfurt. Barcelona is the favorites in this match, but Frankfurt cannot be considered a weak team even though they are currently ranked 9th in the Bundesliga. Frankfurt journey in the Europa League has been very good, they made it into the last 8 of the Europa League after successfully topping the group consisting of Olympiacos, Fenerbahce and Royal Antwerp. Frankfurt also managed to beat another Spanish representative (Real Betis) on aggregate (3-2) in the round of 16.
If Barcelona beat Frankfurt or vice versa, they would meet the winner of the match West Ham vs Lyon in the semifinals.
