Sebastian Larsson has said that he is "happy" playing in England, but that he would be prepared to leave the Premier League during the summer transfer window.
The midfielder's current contract with Sunderland expires at the end of the season, with Stoke City and German side Borussia Monchengladbach reportedly interested in signing the 28-year-old.
The Swedish international told Fotbollskanalen.se: "I am happy and truly enjoy myself in England. In my opinion, the Premier League is still the best league in the world overall.
"Therefore, it is a fantastic environment for playing football, considering all the interest in the Premier League.
"I will sit down with the agent and review the eventual options. If the best option is to move from England, there is no problem with that."
Larsson joined the Black Cats from Birmingham City in 2011.
