Regardless of whatever strategy the coach uses, the most important thing is the final result, as you said, there is nothing embarrassing about defensive strategy.
However, destroying Leverkusen is not an easy thing because many teams have tried it throughout this season and none have succeeded.
Leverkusen is a strong team, we have to admit that and Roma is actually also a strong team when managed by De Rossi but in their last few matches in the domestic league we can see that their performance is a little bad so this is a benchmark for the first leg match they played Leverkusen.
I still favor Leverkusen, I think that's realistic because in terms of overall strength we can see from the start of the season that Leverkusen is much stronger and more consistent.
If you look at the performance of the two teams that are currently quite good, of course it is very likely that whatever the strategy of the two coaches will be destroyed by itself in the match, because indeed both teams are currently at the peak of their best performance, in my opinion it is difficult to say who the team will win in the match because I think both of them must have known each other's weaknesses, So maybe their chances of winning are 50/50, but even so it is certainly not an easy job for Roma to destroy Leverkusen even though they will play in Olympico later, Roma will certainly prepare their defense well because indeed the mentality possessed by the Leverkusen attacker is extraordinary in terms of scoring goals.
In the match later, of course, the mentality factor and also never giving up will be an important factor for both teams in winning, so I think one of the teams that is able to continue to maintain that factor will of course be able to win, in terms of ability and performance, of course the two teams are quite even, so that's why I say if the coach's strategy will self-destruct if the match will be balanced and also fierce, So at a crucial time, of course, the spirit and unyielding attitude of the players will be a very important factor.
