While it is certainly exciting to watch, but the lack of being able to convert on the part of BVB is quite frustrating.
Bartra has been good offensively but defensively I thought he was outplayed several times already in the first half. The best defender had been Sokratis in my opinion. Also I thought Aubameyang and Demele had been a bit poor too. Didn't understand at first why Tuchel started Gomez instead of Goetze, but man Gomez tracked back so many times and was very good defensively. Passluck had been very good too. Rode was solid, so was Castro, but he really lacked the ability to find teammates in the right position to distribute the ball to like Gundogan does, in my opinion.
On Bayern's side Hummels clearly lacks match fitness and is probably quite nervous because of the booing and stuff.
