Capello will lead England to the greatest possible potential that the current talent can offer. Whether that means winning a tournament or not remains to be seen, as at the moment I wouldn't say we can. It looks difficult as well given the lack of time Capello will be able to have the players, if he had access to them a lot more often he could get so much out of the England team.
February international friendlies are a complete joke though. Unbelievabley stupid.
