Khedira was essential in 15-16 when we sold half our midfield to help us get back on track. We never lost a single game when atleast 2 of him, Pogba, Marchisio played (except Bayern, but that was overtime).

And you talk about goals, Khedira scored a 3rd of Higuains goals for us, in the same amount of games, as a mid. I for sure know which of the 2 transfers I'd repeat again if given the chance, and the argie isn't the one
