I don't agree with this fitness crap but happy to stand corrected if I am wrong .
Are we saying players can't improve their fitness im 5 months? How did Klopp implement this in his first season?
I know Rodgers already had them playing a high pressing game and so the change wasn't too big still wondering how he did that.
Klopp joined Liverpool in the October, although they reached the EL final, they finished 8th in the PL, losing 8 times under Klopp. He had a mixed bag of results, some impressive ones. They looked done fitness wise after 60/70 minutes in some games. It took them a while to adjust. As you allude to, a high press wasn’t unfamiliar, to the players, but they still struggled. Their injury list, although they had injuries under BR, it went through the roof, soon after Klopp arrived. They won 1 of their last 5 league games, but focus, I guess was on the EL.
Klopp plays differently now. OGS high press and formations will be similar to Brendon Rodgers Liverpool, judging by what we’ve seen so far, and the few times OGS, has mentioned style of play, in interviews.
