I often see the manager of a winning team making substitutions as the end of the game nears (sometimes as late as during injury time).
The player being replaced is not injured, and doesn't time get added on to make up for the time lost for the substitution to take place?
So, what are the tactics behind this? Is it related to giving the player another cap? (perhaps pay related for an appearance?) Is it a mind-game to try and break up a run of play which may have been in the opponents favor?
