text: why do fans complain whenever a referee makes a vital decision in a match.? every game that ends in favour of one team,the referee is seen to be bias or favouring the winning side.ie the game between bacerlona and asernal of the 17th may 2006. probably because neither team supporters want to loose. they can't blame their own team for not playing well so the referee cops it. no doubt that mistakes can be made by a ref but it goes both ways. they should look at their own players who didn't play well.
