Has Pellegrini got his tactics right?

Pellegrini persisted with playing Sergio Aguero and Edin Dzeko in attack against Roma, but once again this was a tactic that left City exposed to the dangers of being outnumbered in midfield.
This was a problem as far back as last October when City lost 3-1 at home to Bayern Munich, and Aguero and Dzeko both started. City were overrun and well beaten.
The temptation to use both is understandable as Pellegrini has a pair of quality strikers on his hands, but there are undoubted risks against the sort of elite opposition City will run up against in the Champions League and 4-5-1 (with one of the pair sacrificed) may be a case of 'better safe than sorry' against the stronger teams.
Using David Silva and Jesus Navas in the wide areas was ambitious but also offered an open invitation to a side as progressive as Roma. It was no surprise when Navas was replaced by James Milner at half-time and Dzeko followed shortly after, with Frank Lampard being introduced.
Pellegrini's default position is permanently positive but he may have to consider caution or risk City being vulnerable when they travel to face Roma in Rome and welcome Bayern to Etihad Stadium.
