Because stability is important. It took Ferguson three years to win a trophy (and that was "just" the FA Cup), but they kept him and were soon repayed with countless domestic and European pieces of silverware. If Roman was in that position as United chairman there and then, Ferguson would have gone - fact (well, not quite a fact, but you know). I'd much rather win the league and/or CL every season, as United tend to, than keep hiring and firing managers for short term success. Roman has to keep the faith in AVB - look at his age, experience and price tag (not that he particularly cares about losing money/pay offs). Even if he takes his time and only wins, say the Carling or FA Cup, he shouldn't be sacked. He had instant success at Porto, but the Premier League is a different kettle of fish. Roman shouldn't expect us to win the Champions League straight away this year - IMO, that would have only been a possibility under the long-term management of proven people like Carlo, Guus and Jose. I'm not having a dig at Andre, but rather saying we - including Roman - need to stand by him for long, stable success.
