Not convinced Liverpool won't sack him. It's difficult to come back once you get negative press on a regular basis and he's been there for 8 years or something, which is the equivalent of forever in modern football. They might want to bring some fresh air and it's easier to replace the manager than half the squad.
Not convinced Barcelona would sack Xavi for him either but I agree that he'd probably take a couple of years off and see how things pan out. He might also be reluctant to manage a different club in England so, all in all, there's very little chance of getting him but I was curious to know whether people rated him or not. We all have our pet hates (Mourinho, for some) and, in this case, I think my strong dislike for him clouds my judgement.
