Gameiro, who joined PSG from Lorient in 2011, has fallen down the pecking order at Parc des Princes following the arrival of the likes of Zlatan Ibrahimovic and Ezequiel Lavezzi.
Sevilla are reported to be interested in acquiring the 26-year-old - who could cost up to €10 million - and the France international revealed that he is considering a move abroad as he looks to further his international prospects ahead of the 2014 World Cup.
"There is talk about Sevilla. I have to decide whether it would be better for my career to go somewhere else and not be satisfied with my substitute position in Paris," he told L'Equipe.
"I want to play football and score goals. In one year there will be a World Cup and that is a target for me."
Liverpool, Borussia Dortmund, Valencia and Fenerbahce are all rumoured to have enquired about Gameiro's availability, but he was quick to stress that Spain is his number one choice.
"I have opportunities almost everywhere, but I do have a preference for La Liga."
Gameiro - whose current deal expires in 2015 - made 29 appearances for PSG last term, scoring nine goals.
