Where exactly did I say Yaya provided a shield? What he simply provides is another body in midfield against a team that attacks with pace and power, not to add it's a known fact your defence is a bit shite. If his decision was right and he didn't need another body in the midfield, why did KDB get pushed deeper in the second half? Also the second half doesn't justify his decision as you guys managed a single touch in Monaco's box in the whole first half. So much for "pressuring them in their own half", that's not just shit performances, that's shit tactics too. He made a mistake as he's done constantly in Europe since leaving Barca. Two different teams, similar tactics, similar results.
Your defence is a bit shite, your keeper situation is a bit shite and your midfield was plagued by injuries, so he insists on pressuring players who are great at getting pressed with one central midfielder, providing literally no cover to his terrible defence? Genius at work, far beyond other managers. Maybe he's just getting slapped around in the CL because the game isn't evolved enough for his tactics yet.
I don't need to explain to Pep why he's wrong. Other managers seem to be doing that for me.
Edit: Also, calling him out on his bollocks hardly makes me a keyboard warrior, only an arrogant manager would lose 6-1 and then repeat the same mistake a year later. I don't claim to know more about football than Pep, simply that he makes mistakes like anyone else. His mistakes unfortunately seem to be a result of his arrogance though, rather than lack of understanding. Results speak for themselves. You wouldn't understand though, you're infatuated by the fact that he's at your club and all, so I understand, continue on your way.
