Willem II striker Alexander Isak has welcomed interest from Chelsea.

The Blues had scouts in the stands for Willem II's defeat to Ajax this weekend to watch Isak in action.

On-loan from Borussia Dortmund, Isak scored in the loss.

"I have just heard about the rumours, but I have not intended to focus on it. I don't want to let such things affect me," he told Expressen.

"It is clear that it is fun that there is interest from around the world."
