It is a small consolation to know that he has been spared a lot more pain and suffering but today we feel very sad at his passing. It is devastating news for everyone.

He loved the Celtic fans and treasured the relationship he had with them, and he was never happier than when he was out on the pitch.

I can't help feeling there's a terrible irony attached to how a player of Willie's ability could end up with relatively little to show for his career. Today, a player like him, even after seven or eight years, would never need to worry about money again.

Jimmy practically played Inter Milan on his own. There was nothing he was ever frightened of, he was brilliant.

It's an absolute tribute to how hard Kim has worked.
