Pep wanted him gone in 2012 as he could see his focus was wavering. Like people have said, Lucho was able to get one last tune out of him but bar the odd good moment under Valverde in 2018 he's been a semi-retired player since.
No doubt Pique would have been on the chopping block under Pep and about as good as gone if that idiotic board would have backed Guardiola instead of pushing him out. He was a disaster in 2012 and the main reason why the defense that year leaked many goals. Such an airhead and a clown, pity about his talent.
He hold it together as long as he had aces and natural leaders around him like Puyol and Mascherano.
Pep was rumored to want the club to sell Pique, David Villa, Fabregas, and Alves. He was pretty spot on about all bar maybe Alves. David Villa and Fabregas were gone soon after him.
I find it pretty astonishing that Pep sensed the dangers of this team losing motivation and complacency setting in as early as 2012. Here we are 10 years later reaping the consequences of not doing anything about that in a decade.
