Yeah I saw the game, N'Zonzi was great, best game this season for him probably, and I watched plenty of Sevilla games but it is not like they're miles apart, they're in the same bracket, they differ a little bit, I understand if someone thinks N'Zonzi is better but it is more what TheSpecialCnut is after, their press is working well because it is a team-wide strategy, and Sampaoli ignited him. He didn't win the world over at Stoke and went to Sevilla for peanuts.
We (Arsenal) also don't really play the same way, Coq has more responsibility because we line up more offensively, he is more isolated at times than anyone in Sevilla is. Partnered with Santi who is good at always being a playable option it looks simple and you don't notice when Coq wins the ball and makes a simple pass. If his partner (say Xhaka) isn't available and opponents are closing him down he has to take risks with both passing and movement, or passes it backwards, neither look particularly good on the eye.
Xhaka has improved a bit on his availability lately it seems, maybe it comes with confidence, or it is just that we're not under as much pressure lately.
