I quite like how he said it too. He said something along the lines, every new manager says the players arnt fit enough, but that's because Lambert was trying something different. I need my players fitter for the type of football I want to play.
It's been clear, certainly for the last few months, Lambert had been obsessed with possession and shape. Sherwood wants to play with a higher tempo, and press higher up the pitch...which is what I've been calling for.
