Always had a good attack? We scored 50 goals in the entire 14/15 league season. That's appalling. Prior to Klopp joining we were drawing every game 1-1. When we beat Villa 3-2 at home it was pretty much the first time we had scored more than 1 goal in a game for some 6 months. He turned us from being entirely dependent on Sturridge to practically not even needing him. Our defence isn't as good Spurs and Chelsea but we've only conceded 2 more than Arsenal.
He has also created such a system whereas I think Klopp for the most part has a lot of good players he is just playing, rather than players who work well in a system. By this I mean Wijnaldum, he is played as a CM when he simply isn't one and isn't that great there.
Absolute nonsense. United/City/Arsenal all have better players than Liverpool. It's precisely the system and the coaching that has seen Liverpool go above those 3 in the league. So much was made of Liverpool's pre season were they trained and trained on this 4-3-3 and the pressing and movement that's needed. Liverpool and Spurs are the two who are more than the sum of their parts, and that's down to the manager and the system. Who's to say Wijnaldum isn't a central midfielder? Clearly Klopp has had him eye on him for a while and thought he would be great for this 4-3-3 we're playing. And he's been very good there, so I'm not sure how you've come to the conclusion that he's not been great there.
He was a signing for his attacking aspect and not so much his defensive attributes. I think Pochettino has really created a working system and formula out of players that previously were good players, but now look great.
Says who? The only person that can know that is Klopp himself, and if it was true he wouldn't be part of our strongest midfield. Klopp 'created' this 4-3-3 and helped players like Lallana, Henderson, Mane, Firmino, Milner now look great. Pretty much everything you said can be applied to Klopp and Liverpool. Pochettino has done an astonishing job at Spurs but it's arguable that Klopp has done anequally good job at Liverpool. And if it's not arguable, the reasons you gave aren't valid.
