Yuto Nagatomo proved Inter Milan's matchwinner last night.
Inter held off a late Genoa surge to win three crucial points thanks to Nagatomo's second-half header.
This was Week 11's rearranged fixture. The original match was called off after Genoa was one of a number of regions in Italy hit by severe floods that claimed a number of lives.
Proceeds from Tuesday night's match will be donated to the relief fund.
