Inter moved back to within a point of Serie A leaders Juventus with a comprehensive 3-0 away win over Torino.
After kick-off was briefly delayed to allow for water to be swept from the pitch amid heavy rain, Lautaro Martinez scored his eighth goal of the season in the 12th minute.
Twenty minutes later, Stefan de Vrij's first strike of 2019-20 had Inter two ahead and Romelu Lukaku scored his 10th Serie A goal of the campaign after the break to wrap up the points.
In-form Lukaku is the first Inter player to score 10 goals in the first 13 matchdays of a debut Serie A season since Stefano Nyers in 1948-49.
