Atletico Madrid are not worried about losing Matheus Cunha to Manchester United this summer.

United have reportedly made contact with the Brazilian winger over a potential transfer.

But Atleti feel confident about keeping Cunha due to his €100 million ($102m) release clause, per Goal.

The Spanish club will not accept anything less than the release clause.

It is highly unlikely the Red Devils will stump up that kind of cash prior to the end of August.

Erik ten Hag will now have look elsewhere to bolster his attack after losing the opening two games of the season.
