16 trophies in 4 years. That's insane. He managed (arguably) the best team ever in footballing history. However, he was at Barcelona for years and years, learning the insides and outs. He moved to Munich and changed their playing style which only made them worse to be honest, in my opinion they were so much better with Heynckes. City is another chapter where his tactics are showing to be no way near as effective as they used to. No, he doesn't have Messi but he does have Aguero and De Bruyne and they are perfectly capable of winning games on their own. Their defense is a joke at the moment. Guardiola is no way near what he used to be.
This thread might piss some people but that's what I believe. He's a good one but no where near the level he is rated. One of the most overrated coach.
