There's very fast CBs that can more than match players like Mbappe. Koulibaly did just that last season comfortably. Konate, Upacameno, Tah, Van Dyke are all lightening quick and I can name many more. Even De Ligt who isn't quick dealt with Mbappe (Holland V France) even showing him on the outside before outmuscling off the ball. De Ligt can compensate for his lack of pace due to his physicality but Lindelof can't as evidenced by his showing against the 5'9 Cavaleiro.Centre backs as a collective aren’t quick. Players like Mbappe and Cavaleiro are going to destroy the vast majority of CBs in a foot race. You put Tuanzebe up against Mbappe in a straight sprint and he’ll get destroyed too. It doesn’t make Lindelof slow for a centre back.
You can bother him all you like. Anecdotal evidence means feck all. You can do that for every player. Ask GifLord to bring up the clip of 35 year old Carrick smashing Aguero in a foot race.
Tuanzebe would fair better than Lindelof against Mbappe because he's physically stronger aswell as being noticeably quicker.
