Cristiano Ronaldo scored again but went off injured before Lazio snatched an injury-time 1-1 draw against Juventus.
Ronaldo had given the Serie A champions an early lead with his sixth league goal of the season and third since returning at the start of the month after self-isolating due to coronavirus protocols.
But he was taken off with an apparent ankle injury in the second half and watched his side concede a 94th-minute equaliser by Lazio substitute Felipe Caicedo.
Caicedo grabbed a 98th-minute winner at Torino last weekend and notched a late equaliser in Wednesday’s 1-1 draw at Zenit St Petersburg, before capping a remarkable week with another last-gasp leveller to reward Lazio’s dominance after the break.
Ronaldo had set Juve on course when he turned in a Juan Cuadrado cross with just 15 minutes on the clock and he hit the post before the interval as well as seeing a free-kick brilliantly saved by Pepe Reina.
But he limped off in the 73rd minute to be replaced by Paulo Dybala and watched on with ice on his right ankle as Lazio started to assert their authority.
Juve’s defence had held out until Joaquin Correa weaved his way into the area and found Caicedo, who provided late drama with a shot on the turn to stun the visitors.
