Stephan El Shaarawy's stunning goals-per-game average, the fruit of five goals in six appearances. Another Roma player to register a similar impact in his first six league matches for the club was Danilo Michelini, who notched six goals in the opening six games of the 1937-38 season. Michelini scored a hat-trick on his debut against Fiorentina (4-0), then one against Napoli (2-1), Lucchese (5-0) and Atalanta (2-0) respectively. El Shaarawy broke the deadlock on Friday for the second week running after his goal for 1-0 against Empoli.

Mohamed Salah, Stephan El Shaarawy and Edin Dzeko have scored four doubles between them in the last three league fixtures. You have to go back to summer 2009 for a similar collective scoring streak, when Francesco Totti scored two doubles and a hat-trick against K.A.A. Gent and FC VSS Kosice in the Europa League qualifying rounds alongside a Daniele De Rossi double away against Gent. The last time we had a similar run of goals in the league was in 2006-07 during Luciano Spalletti's first spell in charge when Roma strung six consecutive doubles together: Totti (3), Rodrigo Taddei (1), Christian Panucci (1) and Simone Perrotta (1) against Fiorentina, Milan, Catania, Sampdoria and Atalanta.

Their seventh league win in a row allowed Roma to put points between themselves and Fiorentina. The Giallorossi haven't been on a winning streak this long since the second half of 2013-14 – nine back-to-back wins – which came after the golden ten at the beginning of that season. Before these two hot streaks, the last seven-match 100% run in Serie A was between January and February 2010. This season's winning spell has thrown up some interesting numbers: Along with 22 goals scored and five conceded, Roma have been ahead by at least two goals in every game and ended the match one goal ahead only against Sampdoria. Also, Spalletti's men have gone into half-time ahead on every occasion apart from the Carpi and Frosinone matches.
