As Ram's said, we don't even know if we're interested in Fonseca. But some people are so down on the club at the moment that they're willing to believe anything that reinforces that negativity (ie West Ham are a more attractive proposition).
Also, West Ham's porn barons and Tory whore dreamteam always give it the biggun in the media about big names, and then they end up with Bilic or Moyes.
The expectations are clearly different. West Ham would love to finish 8th and would be handing out a 5 year contract. We can't get rid of our manager quickly enough, having finished 8th.
