He is a passive player. If the team around him creates the right patterns and spaces for him to play his style he can be effective, but if they do not then he doesn't have the engine or drive to try to affect the game on his own. If you compare him to Antony, whilst neither played their best you could see Antony has more fight, drive and wants to affect the game.
Another interesting thing with Sancho is at Dortmund he played with high intensity fullbacks and a striker in Haaland who provides constant movement. The energy and drive is provided by the players around him, not by him. It seems he cannot provide that drive and energy on his own.
Lastly I have big questions about his mentality. He does not seem to be a leader or a player that fights to affect a game. Quite quickly we have seen that Martinez, Malacia, Bruno, Antony all have fight and want to be part of a game. Sancho (and Rashford) does not lead or try to take a game by the scruff of the neck. If we want to have leaders all over the pitch then Sancho's place in the team needs to be questioned. I also think only 1 of Sancho/Rashford can be played at a time. We can only afford to carry 1 or 2 players (I believe we are also carrying Eriksen from an energy perspective).
