Mertesacker continues to baffle me. Honestly on paper how is he a good defender? Slow, can't turn, don't really jump well too. Big sized, almost certainly to get eaten up by nimpy players like Suarez and Aguero.
BUT, come the real pitch, he is bloody good. Defies all critics, solid as hell. Totally owned some of those smallish dribblers as well.
This is the best central defence option Wenger has ever assembled imo. Don't think many teams in europe will come close. Only maybe juve.
Asa, Verm and Kos were rock solid against Milan at home last season.
