Kimmich gifted a victory goal to England when he played in German side. He could not do basic defending and was toyed by Grealish and Shaw.
Kimmich was useless when facing Man City except taking the pen (a good one!). He could not hold the ball and could not put the midfield and backline together.
He was once a good player in one or two season then he stopped grow. Physically too weak. No reliable ball carrying skill. Not a reliable defender either.
Yes, he can play multiple positions. But far from world class. But he is the German version of Cancelo as a right back. He is the German version of post heart problem Christian Eriksen as a midfielder.
His lack of ball carrying ability is the reason why Germany did not get out of group stage in the World Cup. There are only two world class German midfielders right now, Toni Kroos and
İlkay Gündoğan.
