Gallas insists he will stay at White Hart Lane for the remaining 18 months on his contract with Spurs.
The 34-year-old told French TV station TF1: “I believe I can play on for another season and after that I will decide on USA or Qatar.
“The MLS was interesting before and I spoke with Titi (Thierry Henry, who plays for New York Red Bulls) but I still wasn’t sure. During this time, PSG made an offer, but I rejected it because of my family.
“But also the Premier League is more competitive. I want to carry on playing big performances until June 2013.
“This is my date to leave the Premier League and this season Spurs play wonderful football and are competing for titles.”
