An unusually profligate Mauro Icardi was the main culprit in front of goal as the Nerazzurri were forced to settle for a 0-0 draw with city rivals AC Milan.
Icardi had one goal ruled out for offside in the first half before missing a pair of sitters after the interval, the second of which came in the 93rd minute.
Converting that chance would have lifted Inter to third, but Spalletti was willing to forgive his captain after edging two points ahead of fifth-placed Lazio in the battle for a Champions League spot.
“I feel good,” Spalletti told Premium Sport.
“The team played a good game where they showed they know what to do, that’s the nice thing. The result comes after.
“We played a good game and we have to do that in the remaining fixtures while having the right ruthlessness.
“If not we’ll go back to people talking about technical ability and there will be another pandemonium.
“I’ve been critical in the past, saying we didn’t play well, but now I see a strong Inter and I’m confident for the future. I’m happy with what they’re doing on the pitch, because right now that’s beyond reproach.
“There are moments where we need to keep the ball where it is, rather than moving it to areas where we’re numerically inferior, there are some choices we need to look at again but the team played with personality.
“There are still things that can be improved, but we need to do it quickly. We still have too few getting on the end of crosses.
“[Ivan] Perisic put in 10 from the left, [Joao] Cancelo and [Antonio] Candreva put in others from the right but we didn’t gamble.
“We didn’t make the right choices, based on where the ball started from we didn’t attack the right spaces at the right time.
“[Roberto] Gagliardini and [Marcelo] Brozovic, the former in particular, have the physical strength to hurt teams.
“Gagliardini has to gamble and try to get on the end of crosses, maybe the cross will be poor but that doesn’t matter because maybe you’ll get two balls you can score from.
“In that respect we could do more.”
Spalletti was also asked about Icardi’s misses.
“There’s nothing we can do, it’s disappointing because the three points would have meant a lot.
“Nothing changes for us, we’ve picked up a point on the others and Milan are still eight points behind, even if they’re still in the fight.”
