Pressing was next to non-existent, now they are pressuring all over the pitch.
The team played passively and timid like relegation fodder after going infront, now they keep going for the throat.
Movement was too formulaic and static, now they are playing without a striker and very fluid movement, Sancho and Hazard having free license to roam, Reus playing something between #10 and #9, Schulz and Hakimi popping up in the middle of the box.
343 as a formation and Zagadou and Brandt (at the heart of the team) surely helped, but for me it goes beyond that, it's just a complete 180 in so many aspects. It's like Favre was sacked and replaced with some Klopp-like motivator. Except he wasn't and now it looks like the guy who couldn't find any answer for 10-11 months found all the answers within a week.
And while I'm busy crying about the ref and Bayern fans are gushing over Coutinho, Leverkusen quitely got two players sent off and lost 2-0 in Cologne. What happened there?
