Returning to the focus of the match between AS Roma and Leverkusen, it is indeed difficult to predict this match, because these two clubs are like balanced clubs now. I'm not sure whether AS Roma will go to the final, but on the other hand I also doubt Leverkusen will be able to beat AS Roma.
Roma don't seem strong enough to beat Bayer right now, I think this match could end in a draw. Bayer may be happy with this as a draw away would give a good chance for the second leg at home. Roma will certainly try to win this match, but they will also keep an eye on the defense so as not to concede at home. EL has always been difficult to predict. Juventus will also try to win their match, as it will be very difficult for them away.
In my opinion, a draw is very possible in this match, Roma and Leverkusen have met 4 times in the Champions League, in these 4 meetings the two teams were equally strong, with 2 draws and 2 other matches won by Roma and Leverkusen respectively. Roma and Leverkusen both suffered defeat in their last match in the local league, in the last 5 matches of the two teams, they were both unable to maintain their best matches. Overall Roma have progressed a bit this season, but ahead of the match against Leverkusen Mourinho men have not performed well.
I hope this fight will be a very exciting and interesting match. considering that this match brought together two coaches between Jose Mourinho and Xavi Alonso. these two coaches, had formed partners when they were still with Real Madrid. Xabi as a player, Mourinho remains as a coach. well, this match is quite an interesting match for me personally than the Juventus vs Sevilla match. referring to what you said, yes, these two teams have H2H history in the Champions League. now, both of them will fight in the semi-finals of the Europa League.
In this match, AS Roma is more favored than Leverkusen. I think it's very natural, because this match will be held at the Stadio Olimpico, headquarters of AS Roma. but if we refer to their matches in the League competition, after overthrowing Feyenoord, Roma appeared in a poor performance without a win in the last 4 matches in the domestic league.
On the other hand, Leverkusen have been in decline in their last two matches in the league. but they have an interesting record when away from home in the Europa League competition, Leverkusen were able to overthrow Monaco and USG. so, I think Leverkusen has the probability to overthrow the home team in this match. well, if we refer to the predicted line-up of these two teams. either AS Roma or Bayern Leverkusen, will implement an offensive pattern system. Roma with 3-4-2-1, Leverkusen with 3-4-3. by the way, referring to what you said. yes, this match has a potential probability of a draw with odds @2.90. but in my estimation, Leverkusen will win this match even though AS Roma is more favourite. well, the name is also a bet, winning and losing is a thing that can. So, I will choose Leverkusen with odds @3.45.
