There are two ways to address the issue of remembrance: One is to celebrate the life, the other is to silent reflect on the tragedy that befell someone.
M*nich was clearly the latter, but, personally, I think Bobby Robson's was the former. In addition, of course, clapping someone off the "field of play" IS a long standing football/sports tradition.
My own father died in June and we held a minute of silence in church, even followed by a referee's whistle (he was a footballer) and, when it came time to carry the coffin out, my sister said, "and now please rise and show your appreciation for a player who played a blinder but now has to leave the field of play." At that, the whole church stood and clapped him as we carried him out. We all thought it was a wonderful FOOTBALL tribute and were complimented on what is often an awkward transition from service to hearse.
I realize this is a matter of personal choice and tastes, so there is no "right answer," but for personal tributes to footballing greats, it seems a minute of clapping and singing "there's only one ............" is a fitting NEW tradition.
Respectfully.
