Inter went for a walk in Salerno and with a 5:0 victory over the home team Salernitana gained four points at the top compared to the second-placed Milan.
It's not the "classic plus four with one more game", because on Sunday, two direct rivals "unbeaten" for the title will meet - Milan and Napoli, which has seven points less than the leaders.
In any case, Simone Inzaghi's team will relax and wait for the outcome of Sunday's derby, and any outcome other than Milan's victory would mean an increase in points advantage after this round.
The ranks of the shaken Salernitana, last in the table, a team that even a move to a lower rank threatens due to an interesting conflict of interest, Croatian Ivan Perišić broke the deadlock with a header after Čalhanoglu's corner already in the 11th minute.
By the end of the match, they were among the scorers Dumfries at 33, Alexis Sanchez in 51, Lautaro Martinez in the 77th. and Galjardini in the 87th minute.
The second goal of the match, scored by Dumfries, had great symbolism for Inter, who for the first time in the club's history exceeded the figure of 100 goals in one calendar year.
The previous record was held by the generation from 1950, which stopped at 99.
The absolute record of Serie A, by the way, is held by the Milan generation from the same year, 1950, which scored 120 goals from January to December.
