Leverkusen's advantages now multiply quite large where in addition to the second leg Leverkusen will play home, they also have an aggregate advantage which must be a little difficult for Roma to pursue, especially the atmosphere at BayArena will definitely make the mentality of the Roma players a little disturbed by the many Leverkusen fans present.
With this condition Xabi will have the upper hand and it is not impossible that he can do what he wants by playing aggressively as usual especially for now their midfield is still very solid but indeed if they want to play safe it is actually not a problem as long as they do not let the safe scheme actually make them lose momentum because sometimes playing safe is a little more difficult than doing an offensive scheme like Leverkusen used to do.
Absolutely, but I remember the game against Qarabağ FK. Out of a sudden that team was able to take the lead against an overwhelming Leverkusen team. Right now nobody would bet against Leverkusen for good reasons as they are indeed stronger, but I think if Roma can score a goal in that game, Leverkusen could get nervous. If the game goes as expected, Roma won't have a chance. But this doesn't mean that the game doesn't have to be played. It is still a step that Leverkusen has to take. Winning 0-2 away from home is of course huge.
But for now they must have learned that underestimating a club is a mistake and they certainly should not do that for now so as I said before, now it depends on how the decision Xabi will take later whether they will try to maintain the condition where their natural scheme is with a fast offensive or play more safe because all scenarios have consequences and they must be aware that Roma will also play hard in this second leg even though Roma are playing away because after all this is the last chance for Roma to get the trophy and as much as possible they will try harder to turn things around in the second leg this time.
There best choice can only be to go all out and play their very high speed type of football. It's not their style to now slow down and hope that it is enough to have scored 2 goals against Roma. I think they would be best advised to attack in this game. They have so much quality that Roma is the team having issues in that game, not Leverkusen. Roma needs a lucky game against Leverkusen.
Against Qarabag it was a shocker though and I am pretty sure that Xabi Alonso thought that this was it. When they conceded the second goal I thought it was over and then they came back with a goal in 93' and 97'. Lol, it doesn't go like that all the time so they better make sure to not allow Roma do too many things against them.
Atalanta vs. Marseille could turn into a thriller. Better chances for Atalanta, but not by much.
