just because Guardiola won plenty of trophies with barcelona doens't mean he is a god-like-manager. what makes people think that he can make chelsea so formidable and get 3 points for every match? do ppl really think this is football manager? whether be it guardiola, avb, rdm and ancelotti, roman should understand that there is seriously nothing as instant/guaranteed success on football level. guaranteed success to an extent probably exists if it is done from the core or a base to start with, example developing a team of youths with great potential and drilling them the loyalty and passion for the club. only with great passion, loyalty, determination and great teamwork on the pitch, players can excel and do well. constantly changing the management does not really help.
