I just watched that game, Inter were poor. Not really sure why Rafinha was on the bench leaving a 33 year old Borja to play between the lines behind a 30+ Eder. As an attacking, er, force...Inter were cumbersome. Karamoh on this occasion was probably the worst player on the pitch too but since he's 19 played 90 whereas Borja and Candreva, the latter their main threat this evening, came off early.
Genoa didn't create much and scored an absurd goal, one Inter centre-back clearing into the other off whom the ball rebounded back into the net. The stats sites rating algorithms immediately plummeted Rannochia's number but he could do nothing. It was a rubbish goal. Second was better, Pandev the ultra cool old fella taking a great touch to take a wild shot from his teammate under control and sending the ball to relax in the bottom corner. Genoa are very solid defensively, a sobering mixture of sheer numbers and structure. Rafinha did in fact move them around and managed 40 odd passes in about 30 minutes of football. Much sharper, much quicker with him but they couldn't find any sort of breakthrough and Genoa deserved the win.
