I did not say that Conte was the Italian Keegan. I said that he would be the Italian Keegan if he loses this season's league title from a position of being 13 points clear at one stage AND fails to win any further PL titles in the future - and let's face it, he won't have a better chance that this. Next season will be much more difficult for him with United and City in the mix, and Arsenal potentially under new management.
Keegan is Keegan because he bottled it and failed to make amends by winning it. Fergie bottled it in 2012 but he more than made up for it with his multiple wins. This is why Fergie is regarded as a winner, while Keegan is regarded as a bottler.
Even Jose, if you class what happened last season as a "bottle job" (well he was never leading the league so the jury is out), he is still regarded as a winner.
Fergie, Mourinho, they are the winners because they've won far more than they've "bottled". The bottlers are Keegan and Rodgers, for screwing up their best shot that they ever had in their entire tenures at those clubs.
