Lavezzi has struggled to break into the PSG first team this year and has been limited to brief cameos from the bench in recent weeks.
Behind Zlatan Ibrahimovic and Edinson Cavani in the pecking order, the 28-year-old, who signed for the capital club from Napoli for a reported 30million euros in July 2012, has been linked with a move away from the Parc des Princes.
With rumoured interest from Barclays Premier League clubs Arsenal and Tottenham, Lavezzi admits he is uncertain over what the future holds but is desperate to give his all for the Ligue 1 leaders.
"I do not know. A player never knows exactly all these things," Lavezzi told Le Parisien.
"But what I can tell you is that I will do everything to change my situation in Paris because I did not give my best shot and I do not want this to continue."
Lavezzi, who will be hoping to earn a place in Argentina's World Cup squad, revealed he must shoulder some of the blame for his struggles this season.
"I did not prepare myself well before the championship," he added. "And the fact that my level is not good is certainly linked to the fact that I'm a bit weak physically."
