If he does, no clapping please. Allthough he would deserve it, lets not help ex players, keep them guessing, that's an order.
Sorry TS, but clap him I shall if he puts in an appearance on or off the pitch against us. Legendary status as far as I am concerned and a shame we didn't have more like him. If I am clapping on my own like a seal, tough titty..........
A player is (or at least should) always give 100% for their club, clapping an opposition player won't do anything to change this in the same way that booing and distracting an opposing player when they take a penalty rarely effects the outcome.
