The whole "Bayern have an old squad that's going to decline" was a load of shite from the start. It'll only decline if he never trades again. But he just can keep trading his older players to clubs that are trying to build, like he did with the likes of Di Maria (to me) and Sanchez (to Valencia).
That's not a dig at Alex btw, perhaps I shot my load too early and should've been more patient, waiting for my younger players to develop. But I traded for a team that would've been good enough to challenge for titles in most worlds, but in this one we're not even close. And now after all this building we're moving backwards, half my first XI has dropped, and we're even further from challenging.
Thinking it was a mistake to re-join this world to be honest, the gap between the top teams (not just Bayern) and the rest is way too big. I owe a few teams players from trades that have already been agreed, gonna stay on until those go through and then I'll re-evaluate.
