Is Pepe Guardiola massively over-rated?

A lot of sports journalists see Guardiola as a genius coach but 'Pepball' has got average to poor results against teams with comparable rosters. When Messi, Xavi and Iniesta were at the peak of their powers, there was no comparable roster. Anyone could win the Bundesliga with Bayern Munich and Pep failed in the Champions League; losing in three consecutive seasons to three Spanish teams, all before the final. Also, see Manchester City's defeat to Monaco last season and their finishing a weak third in the league.

City could win the league this season and indeed they should because they have the best squad, not because Guardiola actually adds any value. His team are a slightly upgraded version of Arsenal; too good for inferior teams but always destined to struggle against sides with similar talent. Whether you love him or loathe him; Mourinho is a better coach and Man Utd will probably win this year's EPL.

Is this too harsh?
