Roma have the advantage with this aggregate 1 score, even so, Leverkusen in the second leg may will be more serious to winning and reaching the final, so Roma still have to be wary of with Leverkusen movements in the second leg. Yes Sir similar to the Champions League, the Italian team this season is very good but it will be very interesting indeed, if Juventus and Roma can be in the final. It will lift the spirits of other Italian teams in Serie A, to be more consistent next season.
This advantage is not completely safe for Rome, especially Leverkusen when they are at home they are far more attacking and so aggressive. Maybe this time Mourinho should strengthen his defense because otherwise they will concede so many goals in the second leg. However, the defensive strategy was not fully able to anticipate the possibilities, Rome also had to appear to attack even though they were already superior.
I think the second leg will be very important for both teams to fight for a place in the European league final. Regarding the Italian team which is currently dominating European competition, this is definitely a good thing and I hope that even next season they must make it to this round and don't lose to either the English or Spanish teams.
To be honest, I didn't watch this match because my attention was on Juventus vs Sevilla. but referring to the statistics of the match, this match took place quite evenly. So, I don't think Rome's 1-0 advantage can be said to be safe. especially in the second leg, Leverkusen played as the home team. at least, they have a strong drive and motivation to equalize the aggregate and even win the game with a bigger score. anyway anything can happen, besides Rome did not play very fantastically.
So, Leverkusen still has a chance to overthrow AS Roma. especially if we refer to the available odds, the bookie favors Leverkusen. maybe in the second leg, Leverkusen can score 1 goal. which in the end the fight continued in extra time, it could even go to a penalty shoot-out. well, I'm pretty sure this fight is pretty competitive. in the end, the two coaches will compete tactics and strategies. although most likely, Jose Mourinho will prefer defensive tactics and rely on counterattacks.
