Fecking hell
The job a a midfielder is to track runners, in this particular instance there was a player with the ball, who played it between the line then ran past two England players,
two fecking players, neither of whom ran with him, that is the mistake in this passage of play, it also happened for Havertz' goal too, a lack of desire by the midfielders to track back or put the press on.
Maguire marks the space he has allowed the German player ten yards on the edge of the box, with the freedom to turn/shoot or pass, which would have been more criminal.
As Delph would say, these are basic principles of football! Play percentages and trust your teammates to do the basics, like track their runners.
