He hasn't been in the best of health for a decade or more. Following on from the recent loss of Jack Charlton, that's the two players critics of Alf Ramsey centred on gone from the 1966 team now. I must admit, I didn't see what Nobby Stiles bought to the England team, but I was too young then to appreciate what are called the dark arts of the game these days.
Only a few weeks ago, I listened to an interview with Nobby on Test Match Special from about thirty years ago where he came over really well as a decent and genuine man who didn't let his fame go to his head - he also loved cricket and was very knowledgable about it.
RIP
