Watch as Lazio fought back from an Ivan Perisic penalty to inflict the first Serie A defeat of the season on Inter, but tension exploded after Felipe Anderson’s goal with Federico Dimarco down injured.
It was an emotional return to the Stadio Olimpico for Simone Inzaghi, who spent 22 years with the Aquile as striker first and then coach.
Perisic opened the scoring from the spot after Elseid Hysaj went in late on Nicolò Barella, cancelled out by Ciro Immobile for an Alessandro Bastoni handball.

The game turned on a moment of controversy, as with Dimarco down after a knock, Lazio scored with Felipe Anderson, sparking a furious response from the Nerazzurri players.
They lost sight of Sergej Milinkovic-Savic, allowing a free header on Luis Alberto’s set play.
The chaos continued after the final whistle, Luiz Felipe shown the red card for ‘mocking’ Joaquin Correa, and was distraught as he insisted it was a misunderstood joke with a good friend.
