Pablo Daniel Osvaldo's stay at Juventus hasn't been the best, but he scored the only goal as the champions took their tally to 99 points by beating second-placed Roma.
Juventus wrapped up the Scudetto with three games to play but they put the icing on the cake with a 1-0 win over Roma and a Serie A points record.
The goal came from Italian international Osvaldo, who joined on loan from Southampton in January.
Osvaldo is unlikely to return to Southampton having head-butted teammate Jose Fonte and he has stressed his desire to stay at Juventus.
After vanquishing his former club, Osvaldo was emotional and left no doubts about his hopes for the future.
"I will never forget this experience."
Later, speaking in the mixed zone to various journalists, Osvaldo was asked whether the financial details may prevent a permanent deal.
Southampton paid £12.8m for the 28-year-old but Juventus would be unlikely to offer anything in that region for him with wages possibly also proving a problem.
"I want to stay here but I don't know what the future holds," Osvaldo said. "Do I cost too much? I don't know - that's for my agent to worry about."
It is possible that Southampton will be willing to cut their losses and accept a reduced fee for Osvaldo, but Spanish side Valencia are also said to be interested in him.
