Speaking to reporters, Tuchel said: "I can see that sometimes he relies heavily on his offensive contributions and gives not so much emphasis on the defensive discipline and effort. This major impact that he had for Liverpool over so many years … if he wants to have this impact in the English national team then he has to take the defensive part very, very seriously.
"Because when we are talking, especially about qualifying football and then tournament football, the one defensive error, the one moment where you are not 100% awake, can be decisive. It can be the moment where you pack your suitcases and go home."
