Not saying Busquets is past it, I am saying Xavi and Iniesta are past it. Do you think they are not? Not that I want to get rid if them, not at all, but the rebuilding of our midfield must not be centered around these two.
Iniesta is absolutely NOT past it.
You put him on the market, every top team in the world will go for him and he will bench any player on whatever team he goes to and he would destroy us if he were to play against us, same could be said about Busi. They may be out of form, but he is absolutely not past his physical capabilities as footballers.
Robben was shit and bottled every big game from 2010-2012, he was absolutely not past it.
Terry and Lampard were horrid the season before and the season during which Chelsea won the CL, they were not past it.
The core of Bayern (also the spine of Germany) were destroyed by Dortmund for 2 years, outclassed multiple times on the national stage, yet neither Germany or Bayern ever gave up on the likes of Schweinsteiger, Muller, Lahm etc... and look where they are now.
Iniesta and Busi aren't finished/deteriorating, that's not even debatable, it's 100% fact. They and the rest of our team is going through a bad spell, but they are still world class footballers.
