He is. He's a better manager than some on here give him credit for - you don't win back-to-back titles in Germany and the league and CL while in England if you're not a good manager. However, I think his achilles heel is running players into the ground due to his maniacal pressing game. That's what happened at Dortmund where it unravelled pretty quickly from a position of great strength, and is what appears to be happening at Liverpool now.
It is possible he can address it unlike at Dortmund because on the face of it,Liverpool have greater resources in terms of refreshing the squad with new signings but I'm not sure FSG will back him enough in the transfer market. The impression I get is that Klopp is on a bit of a collision course with the owners and Liverpool fans should be asking why the likes of Everton are outspending them despite their (Liverpool's) revenues rising considerably over the past couple of seasons on the back of 2 CL final appearances and a PL win. Of course, they've taken a hit during the pandemic with no fans allowed in, and that hit will be greater than most other clubs but even so, every other club has taken a hit too and in any case Liverpool have other lucrative revenue streams. It wouldn't surprise me if FSG are looking at an exit strategy as they'd make a tidy profit if they sold the club.
My question is, does he have a Plan B? It's all gegenpressing, Firmino as a sort of false 9, full-backs getting high up the field, pinning opposition wide players back and pinging accurate crosses in. It works, in the same way Ferguson's tactics worked, because they had the right players who were very good at playing the system.
Gegenpressing is a hard tactic to counter; you have to be exceptionally good to play your way out of it & even we struggle to do it. But you can't do it for 90 minutes, as the history of our games there have shown.
In 2019/20 we were 2 down within 15 minutes;
In 2017/18 we went behind inside 10 minutes;
In the CL game we were 2 down in 20 minutes;
In 2016/17 we went behind inside 10 minutes.
Generally we've looked the stronger in the last 20 minutes of those games but it was also a characteristic of those games that we'd completely go to pieces for 10 or 15 minutes.
Pep has adapted (although not always effectively) and though we weren't comfortable in that first half, we got through it. Having changed things in the second we took the game to them, with the outcome that they (and their keeper particularly) went to pieces under our pressure.
I'm dubious whether Flopp can make the fundamental changes required to his system to get them back on track. He hasn't got the tactical flexibility that Pep has shown throughout his career. If the brute force gegenpressing approach
doesn't work, is there. anything else in Flopp's cupboard? I suspect the answer is no.
