Inter secured a last gasp 1-0 win away at Sampdoria thanks to an injury time Marcelo Brozovic winner after two goals were disallowed in a dramatic finish at Stadio Luigi Ferraris.
Sampdoria were careless with the ball in the final third and a lack of composure prevented them from producing any clear cut chances as Inter made the home side pay for their inefficiency.
Radja Nainggolan had a goal disallowed, with the strike initially given before being called back by the VAR.
Just as the fans and players had appeared to accept the draw, Kwadwo Asamoah struck a wicked left footed effort from the edge of the area after a cut-back by winger Ivan Perišiu0107.
