Let's be realistic here, not sentimental. Stones has been world class but he's been mostly injured last 2 seasons .We should be trying to offload him this summer because we simply cannot rely on him being fit anymore.
People at the club will obviously know more than us. I agree they won't be sentimental though - but if they think he's over the worst of his issues and could play in maybe 25 league games, plus selected other games (35-40 in total), then he needs to stay. If they think they can manage the worst of it, then he can make a huge difference.
He isn't old in centreback terms, he isn't old in appearances terms. If they think they're on top of his issues then that's brilliant.
Huge IFs though.
