The win came just hours after Inter players had been partying following their Scudetto triumph.
"Sometimes happiness gives you an extra gear," laughed Cambiasso.
"It's true we went to bed very late, but thankfully the fixture list gave us the opportunity to play this evening. At 3pm it would've been a very different performance!"
On his rare goal, the Argentine added: "The few times I manage to score, I feel like embracing everyone. We cared so much about getting this victory as even if it was no longer important for the Scudetto, it was crucial for the fans."
