Antonio Conte was left with a "bitter taste in the mouth" after his team conceded a late equaliser at Roma, missing the opportunity to pull clear in the Scudetto race.

Napoli had a chance to go five points clear at the top of Serie A, after second-placed Inter could only manage a 1-1 draw against rivals AC Milan earlier on Sunday.

Leonardo Spinazzola gave them an early lead, but Roma's Angelino volleyed home inside a crowded penalty area in stoppage time to secure a point for the Giallorossi.

"A draw away to Roma is not a bad result, while to see Roma celebrating like crazy after scoring a late equaliser against us also means that we are doing something important here," Conte told a press conference.

"Roma had won seven in a row at the Stadio Olimpico, which is always a difficult place to play at.

"We inevitably leave here with a bitter taste in our mouths because we were in the lead until the 92nd minute without really being under pressure."

Since the start of 2020-21, Roma have scored more goals from the 90th minute onwards than any other team in Serie A (28).

Despite the frustration of seeing two points slip through their fingers, Napoli's seven-point haul from tough matches against Atalanta, Juventus and Roma earned praise from Conte.

"These things happen, it's part of the growth process for these boys. It's another point in the locker and we'll move on, happy with what we're doing and the gradual improvement," he said.

"We have to learn that the details make the difference and we have to work to learn from that."

The former Chelsea and Tottenham boss added the transfer window had created instability, with Napoli having sold Khvicha Kvaratskhelia to Paris Saint-Germain last month.

"I've seen that the transfer deadline has been moved to February 3, it's getting longer rather than shorter and it's an absurd period for coaches," he said.

"It creates instability and that is not something we want."
