"Am I happy? No, we deserved three points," he told Sky Sport Italia.
"As with Lazio, it was another good performance and we attacked Inter high up the pitch. If we had believed in ourselves a little more, we could've hoped for a win.
"[Inter coach] Walter Mazzarri did well to say we played better because Sampdoria were superior today and that shows through in the statistics too."
Today's result means that Sampdoria remain in 19th place in the Serie A table with 11 points from their first 14 games.
