Acquafresca struck against his parent club before Zlatan Ibrahimovic's equaliser and later said: "We prepared for this game thoroughly and you could see that on the field.
"This draw is a great result for us, even if we could have been a bit more clinical. I wasted a really great chance, but I am only 21 and have a long way to go yet."
It was a particularly special game for Acquafresca, as his contract is owned by Inter and he is only on loan to Cagliari.
"Certainly playing here gave me extra motivation and I am happy, as I think I proved one day I can wear this shirt in the not too distant future."
