Having an experienced coach or not doesn't seem to be a guarantee for Sevilla. Because after all, the fact is that Sevilla can still qualify for the final match this season and thus, Sevilla don't have a problem about their coach. But yes, to predict it will still be difficult, because Sevilla and AS Roma have factors that can be superior as well.
Therefore, I think choosing which team to bet on might be able to consider how this team can qualify for the final match. Because if so, at least I would still choose Sevilla to be able to win because to be honest, I'm still impressed with the way Sevilla beat Manchester United and also Juventus.
As far as my observation goes, Sevilla's victory over United was a stroke of luck. whether it's in the first leg, or in the second leg. if, United did not make a blunder in the first leg. and had United not suffered a number of injuries, it would have been a very different story. after that other luck, Sevilla against Juventus whose performance was really very messy. in the end, Sevilla has the right to advance to the next round.
However, that doesn't mean Sevilla's luck just comes without hard work. they do their job very well, and they give their all for one goal, namely to win every game after game. at least, I have to give them appreciation for what they show.
but to be honest, based on my personal assessment that AS Roma will win the final match later.
IMO, in terms of players, tactics and coaches, AS Roma is superior to Sevilla. Unfortunately, I don't like Jose Mourinho's style of bus parking formation.
