When we talk about the 'problem' of Vincent Kompany, I don't think it's a coincidence that after a few months of him being seriously involved with the first team, both Stones & Otamendi became miles better in their decision making of when to commit to tackles/interceptions & also at talking/organising.
At the moment, VK will once again be mostly concerned with his own fitness & career, but when it does come to an end, I think he could, if used, have a big influence as a member of the coaching team.
