I'm very optimism Olympiacos will beat Fiorentina, they have El Kaabi, he's the top scorer in Conference League, so Olympiacos is the team that has an aggressive play style.
This competition doesn't seem to be the right one for Chelsea, but it's much better than last season without any European competition at all, I'm pretty sure Chelsea will be the biggest favorites this season, especially since they have reshuffled the coaching staff and with a new coach
Pochettino is the one who bring Chelsea into this level, I doubt they will be better in the next season when we don't know how their performance with new coach. Tuchel with Bayern Munich is the example, even though Bayern Munich is the strongest team in Bundesliga, they failed in this season after win streak for ten seasons.
Fiorentina vs Olympiacos will be the last game in the conference, both teams will try their best to be able to end the season with the championship trophy this season, currently Fiorentina are certainly the favorites to win the game with all their experience in the Conference League so far, last season Fiorentina failed to win the Conference League after they were defeated by Westham in the final and this season is certainly an opportunity for them to avenge that failure And won the championship trophy this season, Olympiacos who appeared surprisingly able to beat Aston Villa in the semifinals, so it is indeed quite surprising for all of us because Aston Villa has been a strong candidate to win the Conference League because of their good performance this season.
But I personally prefer Fiorentina to win the Conference League this season despite Olympiacos success in eliminating Aston Villa.
Speaking of Chelsea, of course in recent seasons they have been in bad shape, so it is indeed difficult to say if Pochettino's achievements this season are not good because no matter how bad Chelsea performance is, he managed to bring Chelsea to play in the Conference League, but unfortunately Chelsea achievements this season have not been able to make Chelsea owners satisfied so Pochettino was fired after the season ended.
