I agree in a sense, but Giggs didnt 'build up' anything. It's not like he was out pushing old ladies around in the wheelchairs, or banging on about being the pefect husband. The media and people did that - what was the alternative, delibrately have the odd messy piss up? Get filmed abusing a waiter? He kept a low private profile throughout his career after an initial crazy level of attention, likely not with any intention to deceive. Players, not just Giggs, dont owe us anything and if we decide to make some sort of moral hero of a guy because he isnt a scumbag cliche of a footballer, then we sort of deserve to be let down.
Side note, Patrick Kluivert was a genuine superstar footballer in the 90s, playing for some of the biggest clubs in the world and going on to be assistant manager of his country for 2 years. If anybody football fan doesnt know who he is, they were very likely born after the year 2000.
