Sorry, I was thinking that it was 9 matches, which is basically a quarter of the season. As I said and as Junction said, it was also because of the results at the end of the previous season. When you're rock bottom after 8 games of the season then you're in trouble, wait much longer for it to turn around and you're risking an awful lot.
I don't disagree with Jol's sacking being badly handled, or him being incorrectly blamed for much of what was wrong with the club at the time. However, the signs were the club was going in the wrong direction at the time and all the voices at board level were putting the blame on Jol(a lot of the fans were too, I recall). It was Jol or Comolli and Levy sided with the latter.
Even if you take Jol and Ramos' sackings as being the reason for the team's performance that season, Pochettino could lose the next league games and have far more points than Ramos did when he was sacked and if he took 1 point from the next 5 he'd have more than Jol. Will Levy sack Pochettino if we lose our next 5 league games? Well on past evidence you'd have to say it's a strong possibility and he'd deserve it too because it would be a terrible start, we're along way from that though.
The reasons I don't think it's discussion worthy is because it's a hypothetical based on a worst possible outcome and an extreme one at that. There's not a manager in the league that wouldn't be under pressure after 9 games without a win, regardless who the chairman is. It's a reaction of negativity to look at our next 5 games and think we'll go without a win. City are 4 without a win too and I bet their fans aren't speculating about worst case scenarios and their expectations are much higher than ours. If we put half the energy that we waste doom mongering into getting behind the team we might actually have a good atmosphere at the stadium, no one's quicker to knock Spurs down than our own fans and that to me is sad.
