A defender on the bench if you were away and a striker if at home.
Always interesting if a keeper went off. A brave outfielder would don the gloves.
Didn't Dwyer start up front in Tehran back in the day?
No such problem these days. Too many subs if you ask me. Big teams hover up players to be in the squad, many who will never even warm the bench.
One of the problems with the depth we've got now is that youngsters don't get a sniff. We could do with a youngster or two on the bench for experience with the odd 5 mins here or there if appropriate.
