I fully believe Booby insisted he not expend energy tracking back and putting his foot in. Even if he didn't he certainly didn't demand he do it. The first time he stood looking gormless as a player sauntered past him Guardiola, Mourinho, Klopp etc etc would absolutely lose their heads with him and maybe even drag him off. People are neglecting to admit just how bloody bad Martinez is at this management lark and how managers DIRECTLY influence player performance. We'll see what Ross is all about next season.
