Mauro Icardi scored four times, including a first-half hat-trick, as Inter Milan thrashed Sampdoria.
Ivan Perisic put the visitors ahead when he headed in from Joao Cancelo’s cross before Icardi, who played for Sampdoria in 2012-13, scored a penalty.
The Argentine made it 3-0 a minute later from Perisic’s pass and completed his hat-trick in the 44th minute.
Icardi volleyed in his fourth of the match and Inter’s fifth early in the second half from a tight angle.
The result moves Inter up to fourth in Serie A as they aim to take one of the four qualifying spots for next season’s Champions League.
