Borussia Dortmund striker Alexander Isak has opened the door to a move to Chelsea.

The Swede, currently starring on-loan with Willem II, is being scouted regularly by Chelsea ahead of the summer market.

And aware of the interest, Isak says he's happy with the speculation.

"I want to play for a very big club, in a big championship," said Isak.

"I will look at my future at the end of the season."
