if we are talking about getting the maximum from players and would a new coach help then I say the answer is yes. Currently we have FL playing Timo Werner out wide, that in itself is a total fuck up for a start. What comes with that is having chase back and do more fucking donkey work, no wonder he look dead on his feet. That's another point, he's not rested Werner and game managed him, take for example Salah, Klopp did this with him v Palace, benched him and fetched him on to score.
Frank also played Reece James and Chilwell injured against Arsenal, that is another huge fuck up and adds to the list of questions that need to be asked...what the fuck is FL doing and why is he pushing players into the ground.
And maybe if a new coach arrives he would give instructions from the sidelines rather than stand motionless and idealess like a complete waste of space.
