There's no point taking much of what Ole says in pressers at face value. He also said Chris Smalling would be reintegrated into the first team squad and Alexis Sanchez would come back and surprise people. After Wednesday night's game he was bigging up Martial.
All Ole's answers are designed at promoting squad harmony, diffusing journalist questions or diverting attention onto something else e.g., today reminding people Klopp moaned about our penalties. Much easier to blame Klopp than blame the referees but the effect will be the same: scrutiny on penalty decisions we're denied gets increased.
Anything he says about systems, who might play with who or who might not play, just take with a pinch of salt.
