Mazzola would continue his form in the 1947–48 season, and after the first seven rounds he was top scorer with eight goals. On 5 October 1947, at the Stadio Nazionale in Rome, Torino closed the first half with a score of 1–0 for the "Giallorossi"; returning from the locker room, Torino scored seven goals in 25 minutes, three of which were scored by Mazzola, who was forced to leave the field prematurely, amid the applause of the entire stadium due to a thigh strain. His physical problems continued in the months of November and December, yet Mazzola continued to play, offering repeated discontinuous performances. On 23 May 1948, the match against Triestina in Trieste finished goalless; Mazzola refused to pass to his teammates, who showed impatience for his actions. Various interpretations of this event exist: besides the simple justification that the Mazzola wanted to rest, as he was tired and struggling with injuries, there were also rumours that he intended to end his relationship with Torino and move to Internazionale. Amidst this, Torino would go on to win their fourth consecutive title with five rounds in advance, with Mazzola scoring the decisive goal in a 4–3 win over Lazio. Mazzola finished the season with 25 goals as second top scorer behind Giampiero Boniperti.
