If manchester united was not doing some mistakes and i think that MU still becomes the most favorite club right now. Juventus is not so good in the domestic league as well as sevilla. The only problem that may become a serious problem for juventus is not about how how to win against sevilla but how juventus will able to beat a team that was always being so lucky. It has proven that if sevilla was always so lucky in the previous matches against MU and recently athletic club. Sevilla seems to become a new team that was always relying on its luck. The consistentcy becomes the main requirements by juventus to beat sevilla. Juventus shall not underestimate sevilla at this moment.

I think that the win against sevilla may able to make juventus to win europa league. The match between roma vs leverkusen is also interesting enough like sevilla vs juventus.
Sevilla has won europa league six times. that might become the reason why it was always able to leave from the difficult situation.
