Eibar goalkeeper Marko Dmitrovic says Kepa Arrizabalaga will prove value for money at Chelsea.

Chelsea made the Spain international the world's richest goalkeeper transfer last month when signing him from Athletic Bilbao last month.

Asked about the €80m paid for Kepa, Dmitrovic insists it was money well spent.

"If there is so much money, so many sponsors ... those amounts seem very high, but in football they are normal," he told AS.

"If a team like Chelsea has paid so much for Kepa, it's worth it."
