Ivan Perisic's equaliser earned Internazionale a 1-1 draw at Spezia on Wednesday to move Antonio Conte's side one step closer to the Serie A title.
A bad error from Inter goalkeeper Samir Handanovic, for the second match in a row, allowed Spezia to sneak into a 12th- minute lead through Diego Farias.
Inter piled men forward and the pressure told as Perisic arrived at the far post to level six minutes before the break after more great work from in-form full back Achraf Hakimi.
AC Milan's home defeat by Sassuolo earlier on Wednesday opened the door for Inter to stretch their lead and although they failed to win, the league leaders now hold a 10-point advantage over their city rivals in second with six games left.
After the match, Conte criticised both the proposed Super League and UEFA, insisting you must earn your right to qualify for competitions, while questioning the use of funds by European soccer's governing body.
The proposal fell apart after an extraordinary few days, with Inter becoming the first Italian side to follow English Premier League participants in withdrawing from the project.
Conte did not like the idea that teams in the league would not have to qualify for European competition, but also questioned UEFA, who lobbied against the Super League proposal.
"The Champions League and the Europa League must be played by those who deserve it," Conte said. "First of all, sport must always be meritocratic.
"But UEFA organises all the competitions and reserves only a small part of the money to the clubs. The clubs must be rewarded more appropriately. UEFA does not invest anything, the clubs, yes."
Spezia are safe and stayed 15th in the standings after another impressive result against one of Serie A's top clubs.
