These debates don't half get repetitive and your comment is just as misleading IMO.
We all know Yaya's contribution visibly dropped last season but, along with Silva, he was the guy who made most passes per game; previously he was out front and making way more passes.
He's always tended to job about but a lot of his movement is actually very intelligent. He is masterful at both making himself available for the pass and at picking up second balls.
Yaya has been on the decline since we last won the title and it was a fairly steep drop last season. The question, if he stays beyond 31 August, is whether that decline can be reversed by him and Pep and the coaches? It would be a temporary reverse but we only need that because he will certainly have gone by next July, at the latest.
Yaya has been a shot bolt the last two seasons. The games and players just passed him by and he did seem to spend way too much of each game slowly jogging back up field. Statistics don't prove anything much when it comes to passing with us. We've spent two years pissing about with ineffectual possession for its own sake, no doubt racking up awesome passing stats. I rely on my own eyes and apart from the odd cameo Yaya hasn't looked like half the player he was. Or even wanted to be when it comes to fitness levels. He has been awesome and integral but he is now entering his third season too long phase for me.
I would absolutely love to be wrong but I don't believe any amount of training can take four years off his legs. And for Pep's pressing game that is what is needed.
Selfishly I just don't want to remember Yaya as a forlorn figure shambling slowly around after the game and being brushed aside by players not fit to tie his boots. I want to see him having a glorious Indian Summer in a slower, less physical league and in a team that plays to his remaining strengths.
