WATCH: Antonio Conte loses it! Napoli boss has to be restrained by referee after fuming at Olympiacos players over touch tackles in friendly

During Napoli's 2-1 friendly win over Olympiacos on Thursday, Conte had to be restrained after taking exception to Ayoub El Kaabi's late challenge on Amir Rrahmani. Following another bad foul, Conte snapped, and a melee ensued as the incensed former Chelsea manager laid into the striker and the officials for not stamping this out of the contest.

While Napoli got the win, Conte may be concerned by Romelu Lukaku limping off the pitch after suffering an injury. The former Inter man was clutching the back of his left thigh, and reports suggest the striker may miss his side's Serie A opener next weekend. 

Conte, who appears to have not lost any of his fire and passion going by this incident, will hope his Napoli side can start the new season with a bang when the Serie A defending champions take on Sassuolo on August 23.
