Sarri's second spell at the Olimpico has already proven difficult. Limited by a summer transfer embargo, his team has taken just one win from three league outings, falling to Como on the opening day and Sassuolo last week, despite putting four past Hellas Verona in between. Pressure is mounting on a squad that has claimed victory in only two of their last 13 home fixtures, though they remain unbeaten in eight straight 'home' derbies - a club record now under serious threat.
