Roma's bid to break into Serie A's top three at the halfway stage of the season was thwarted in part by two video assistant referee decisions as they drew 1-1 against Sassuolo.
Eusebio Di Francesco was leading the Giallorossi against his former employers and it was another man to have switched to the Stadio Olimpico, Lorenzo Pellegrini, who opened the scoring.
After the break, Edin Dzeko thought he had scored his ninth goal this term but VAR decided he had been offside and, minutes later, Simone Missiroli levelled for Sassuolo with a well-placed header.
