That really is one of the worst articles I have ever read about football.
He has a go at supporters for criticising their own club and manager for daring to question what is going on, and then goes on to say why people don't need to support the same club if a better club comes along.
Someone should explain to him that the supporters are the club, and they are the only thing that remains constant.
Not the players, managers or owners, who in a lot of cases aren't supporters, just mercenaries or opportunists.
Also, If people invest their time and money going to matches and buying merchandise then, if things aren't going well, they have every right to complain.
The fact he swapped from Man U to Arsenal tells you everything you need to know about this idiot.
