I understand that managers often like to put a player on late in the game in order to slow the game down and waste some time, but what is the point of putting on a player with a couple of minutes on the clock if you are chasing the game? No matter what you think of Ramirez he is hardly likely to make an impact in five minutes. I am not one of the Koeman Out brigade but I wish Ron would give subs a proper chance to make a difference on the pitch.
