Inter Milan bounced back from the defeat to Sassuolo by humiliating Frosinone 5-0 away in Serie A on Friday, with top scorer Lautaro Martinez ending his goal drought.
Inter had clinched their 20th Serie A title with five rounds to spare but were stunned by Sassuolo 1-0 last round.
Davide Frattesi put the Nerazzurri ahead in the 19th minute through a counter-attack, before the Italian international set up another for Marko Arnautovic to double the lead on the hour mark.
Winter signing Tajon Buchanan netted his maiden goal with a curler in the 77th minute, before Lautaro scored his first Serie A goal since February, while Marcus Thuram put the icing on the cake with a solo run.
