Lazio played a thrilling 2-2 draw with Sporting Lisbon, but lost the Trofeu 5 Violinos on penalties.
Stefano Pioli’s side visited the Stadio Jose Alvalade in Lisbon for this summer tournament.
The hosts took the lead after just five minutes when Andre Martins snuck up behind Diego Novaretti and Stefan Radu to meet a Fredy Montero cross.
Bruno Pereirinha wasted a golden opportunity, but moments later Lazio equalised in chaotic circumstances. Novaretti flicked on a Cristian Ledesma corner and Keita Balde Diao hit the post, but Stefano Mauri pounced on the rebound.
Federico Marchetti made a hash of his attempts to dribble Martins, bringing down the forward for an inevitable penalty that Adrien Silva converted.
Felipe Anderson and Danilo Cataldi wasted great chances, but deep into stoppages 18-year-old youth team player Mamadou Tounkara waltzed round Rui Patricio to make it 2-2.
The trophy was therefore decided on penalties, Sporting winning 4-2 with Keita and Tounkara efforts parried.
