I'm sorry, but saying he lacks brain cells is completly ridiculous, and only shows you never really watched him, you've seen his games maybe but didn't really observe.Ultimately he cannot even make that simple pass, and no it isn't because he's in decline. It's because he has never had IT.
He cannot weight even a simple pass. Hasn't got the brain cells to angle it. That's not decline, not being able to play a pass.
Btw I actually watched a few games under Xavi, when he was the most criticized, and found it too painful to watch all his wasted movement and frustration because of it. He had to downgrade his football IQ in real time to even try to click with that attack, now it`s better because Flick thinks for them but really, must have been a shock after playing with Müller for so long.
Lots of what you say is like that btw, flat track bully in Bundesliga, when he did exactly the same thing to teams from PL in CL. Not decisive in CL games, there are plenty, prime Kane better etc etc. Too much to disagree to even try to debate that, just a flood of wrong tbh.
