Osvaldo joined Southampton from Italian giants Roma for £15million in August and the striker then described the move as a ‘dream’.
But the People reports that Osvaldo is considering leaving because of the physical nature of the Premier League.
He said: “Football here is so physical, but it doesn’t have the technique and quality that is has in Spain.
“I’m already thinking about moving back to Argentina. I want to play for Boca, that’s my dream.
“I have been dreaming about wearing Boca’s shirt during my entire life.”
