Sahtior x Sevilla
I think these are 2 of the most well organised teams in the competition. Sahtior has a classic bot somehow rare success recipe. Hard working and intelligent defensive players, from Ukraine or other Easter European countries, and creative Brazilians in midfield and attack. Their coach is a Romanian, Mircea Lucescu, he's been there for many years. He is a decent tactictian, but what he excells in is player management. He is kind of an Arsene Wenger, for his brazilian players. He takes care of them, talks to them, takes them to different visits, does his best to help them adapt. And they repay his faith. It's incredible to see Sahtior in the semifinals, considering they sold players for over 90 milion, Teixeira, Douglas Costa and Luiz Adriano, and did not buy anything!
Sevilla is coached by Unai Emery. They have 0 hope left in the league, and will focus fully on this game. Emery has a rotation policy, but in this case, in this particular game, he will go with his best line-up, and he can, because he does not have injured players.
I think Sevilla is too good, and although i like Sahtior, i can not see the Ukrainians winning. Their squad is too weak. They were lucky to play weak teams until now, like Anderlecht or Braga.. They will struggle in this game.
