Liverpool were sent a warning ahead of their Champions League second leg this week as Inter Milan thumped Salernitana 5-0 in Serie A.
Lautaro Martinez celebrated the end of his goal drought with a hat-trick and Edin Dzeko scoring twice to wrap up the win over the league's bottom side at the San Siro on Friday.
Victory gave Simone Inzaghi's side a one-point lead over Napoli in second and third-placed derby rivals AC Milan, who meet on Sunday in Naples. Salernitana remain rooted to the bottom, 10 points from the safety zone.
