No i disagree. Kroos tackles more, intercepts more, makes less fouls per game (based on whoscored stats), and that's with Casemiro in the teamRakitic was and is still defensively better than Kroos
And he is able to complete 90 minutes without running out of gas like Rakitic
Just because Rakitic is better defensively than our other midfielders that doesn't mean he is the best in the world at that.
But he wasn't doing that in Sevilla, why would we buy a player to give us effort if we don't see that effort in his team. In Sevilla he had M'Bia and some other guy doing the dirty work behind him while Rakitic would play with the strikers
Kroos wouldn't have been able to do that? The guy played DM in his first season at Madrid and did well, an automatic starter for them throughout
So what?
I could argue Kroos was better defensively for Bayern than Rakitic was for Sevilla. Got any proof otherwise
