Champions give a losing record
Lazio suffered their worst ever home defeat as champions Inter Milan stormed to a 6-0 victory in Rome.
Lazio started the night on points with Inter and are top of the Europa League table, but had no answer to an impressive attacking display from Simone Inzaghi’s side.
They were unbeaten in 12 home games and hadn’t lost in front of their own fans since March.
Hakan Calhanoglu put Inter ahead in the 41st, following a handball penalty, and Federico Dimarco doubled the lead before the break with a volley.
Nicolo Barella slotted home to make it 3-0 six minutes after the restart before Denzel Dumfries scored two minutes later and Carlos Augusto and Marcus Thuram completed the rout late on.
Inter remain third in the standings with 34 points from 15 games and Atalanta lead by three points with a game in hand.
Lazio’s previous home defeat record was a 5-0 loss to Fiorentina in 1959.
Their three biggest Serie A defeats have all come against Internazionale: that defeat follows 8-1 (1934) and 7-0 (1961) defeats at Milan.
