Well, one can only speculate, but I think one of core philosophies is to build sides around players' strengths. In the first game against Plymouth, I got the feeling Ojo played at too languid a pace, he didn't take men on as soon as he got the ball and generally played at an intensity that was manageable for the Plymouth players, while Jurgen wanted him to play quicker, faster and commit players into defending in 1v1s. That's my impression based on what Jurgen said and the difference in performance between the first game and the second game where Ojo beat that defender three or four times after coming on and generally committed him into a 1v1 soon as he got the ball.
