The influence of the technical directors is indisputable, but there is almost no difference in the squad between the two teams. Because both teams consist of very high-quality players. I especially like Bayern Munich's squad more. Barcelona has very high-quality players, and it will be an extra meaningful match, especially for Robert Lewandowski. Because he will be playing against his former team Bayern Munich, where he introduced himself to the world. He will probably want to score goals to prove himself, so I think it will be a good fight.
Even when I see that Barcelona may end up winning the match if experience is to be used to rate the outcome of the match, I still think it may be an even encounter that every team will play to their best and the best team will eventually win it in the end. The Barcelona team has those quality players than can win the match for them just like the way Bayern Munich also has those qualities in their players to also win the match. It is going to be a tough fight as you’ve said, and Robert Lewandowski will want to show to his former team how good he is till date. Vincent Kompany has a lot to do in this match because of his inexperience, I just hope he can do something about that and come out victorious in this match over the experienced coach.
