I wholly agree with the comments made on "faking injuries". Might I make another suggestion. I do get angry, when with the 90 minutes gone, managers start making totally unnecessary substitutions just to waste time. If the player is on the far side of the pitch, he can take at least a minute to jog wearily off the pitch. I currently live in Spain and I watched a match recently when, with 30 seconds to go the manager made a switch, the player jogged on to the pitch and the ref blew for full time. Farcical. I suggest when 90 minutes are up, NO MORE SUBSTITUTIONS, unless for an injury.
