I'm sorry but when it comes to him so much gets overstated and exaggerated.
The word "immense" is tossed around about his defensive presence all the time and it ends up that he's made 1 tackle, and if you watch closely a vast majority of his defensive actions consist of cleaning up loose balls. And one needn't even bother bringing up the offensive end.
Sevilla had more shots in the second half when Rakitic was on than the first. There was no significant change in our defense because of him, if anything mostly because of how much the game slowed down and became static possession so less end to end.
