Borussia Dortmund defender Neven Subotic has admitted his interest in a move to England, revealing that he wants to test himself in what he believes to be the most difficult league in the world.
The Serbia international still has two years to run on his current contract with the German champions and insists that he is happy at Signal Iduna Park.
However, Subotic, who was heavily linked with Chelsea during the January transfer window, would relish the opportunity to ply his trade in the Premier League one day.
"It's just a thought, if it fits at some point," the centre-half told Kicker. "I want to compete where it's hardest. I think the way they play there is cool."
Dortmund have lost Shinji Kagawa this summer but they have been bolstered by the arrivals of Marco Reus, Leonardo Bittencourt, Julian Schieber and Oliver Kirch, while Mario Gotze and Mats Hummels have both committed themselves to the club in recent months.
Consequently, Subotic is confident that Jurgen Klopp's side will prove just as competitive and united as they have been in recent seasons.
"We have been particular [in recruitment] so that we don't get a diva in the team," the 23-year-old explained.
"I see no reason to change that. This could happen only with an aggressive character. Reus is a humble kid.
"And the guys who got new contracts absolutely deserve them. I do not begrudge them that. I know how much they have worked for it. Extending a contract on better terms is just a recognition of performance."
Subotic joined Dortmund from Mainz in 2008, and has won 31 caps for his country since making his international debut three years ago.
