Last season defeat in the final by Westham is certainly a lesson for Fiorentina this season not to make mistakes, last season Fiorentina made it to the final and I think they will be able to do it again this season, currently Fiorentina has a 3-2 aggregate advantage from Brugge, indeed mathematically Brugge still has a chance to qualify because they only need to aim for 1 goal to be able to make the match continue to extra time later, But even so, of course Fiorentina had the advantage even though they narrowly won in the first leg, statistically in the first leg I saw that Fiorentina was superior on every line and I think Brugge was only lucky to concede 3 goals in that game.
Surprising results did occur in the Aston Villa match, from the beginning of the season of course Aston Villa became the favorite to win in the Conference League because indeed they were able to beat strong teams, not only in the Conference League even Aston Villa was able to surprise all of us in the English League, the defeat to Olympiacos made us all surprised because actually Olympiacos is not a strong enough team at this time, So I think in the second leg Aston Villa still have hope will be able to turn things around later.
Fiorentina is strong enough to win it, but it all depends on who they face. They are facing Brugge right now, and 3-2 is a good start but it is not guaranteed that they will win the second leg and go to finals, they need to realize that Brugge is not a simple team, they are a good strong team and they have the possibility to do a lot better.
We should realize that we are going to end up with a problem on the other side too, sure Olympiacos won the first game, which nobody saw it coming, but that was 4-2 as well, meaning it is just 2 game difference and on the second game we could see Aston Villa go to finals, wouldn't be weird because they are expected to win. If all goes well, best case for Fiorentiona would be beating Brugge and then facing Olympiacos and beating them as well.
So far Brugge does have a lot of experience playing in the Champions League and also the Europa League, while this season is Brugge first season playing in the Confederations League, Brugge mentality in playing in European competitions so far is not in doubt but so far we have also not seen any extraordinary achievements from Brugge while playing in European competitions, Fiorentina are not safe yet because they only narrowly won in the first leg but I think for now they have better hopes to qualify for the final, Fiorentina were able to perform quite well in the first leg but unfortunately they have a little weakness in defense so I think Fiorentina will be able to find the right solution to overcome this in the second leg, In the second leg Fiorentina only need to score at least one goal to be able to secure their escape, of course, on condition that they do not concede again.
The loss of Martinez had a huge impact on Aston Villa in the first leg match, Martinez, who had to be absent due to card accumulation, had to be replaced by Aston Villa second goalkeeper and as a result, 4 goals directly hit Aston Villa goal in the game, as a fan of English football, of course I hope Aston Villa can make a comeback in the second leg later, Although difficult of course Aston Villa still has hope to do it, with a 2-goal advantage and playing at home, most likely Olympiacos will try to play defense so if this is done of course it will be easy for Aston Villa to exploit Olympiacos defense later, for the final later Fiorentina vs Aston Villa is of course the ideal final in my opinion but of course all possibilities can happen including what you said.
