I was one of a few posters saying we could see those two as full backs. I also suggested we could go 3 at the back as this would be the best way to get Silva and De Bruyne both in their favoured central position at the same time.
But it was all speculative, I never dreamed he would have come up with such a fluid system in only two games. We're essentially playing 2 different systems in the same game! On Saturday it was like a traditional 433 when out of possession and a 1950s style WM when in possession. On Tuesday, Kolarov overlapped a lot more than the other full backs, while Zabaleta was tucking inside.
The genius of this style of play is that it gets our two most talented players - Silva and De Bruyne on the pitch at the same time, but it also addresses the biggest weakness of playing them together - being vulnerable to counters through the middle.
The thing that's so impressive is that he has analysed Sunderland and realised there was no major threat from wide, so sured us up in the middle. Steau's biggest threat was their right winger who loves to bomb forward, so Guardiola's answer was to have Kolarov piling forward exploiting the space that had been left. Against Stoke with Shaquiri being one of their best players, I assume we'll see something different again. We're so lucky to have this guy, he is from a different planet tactically.
