Atletico Madrid are refusing to consider selling Jan Oblak this summer.
Manchester United have been linked with Oblak as they face losing David de Gea to Real Madrid at the end of this season.
Oblak's agent has confirmed "an offer from England" over the last 48 hours, but Atletico president Enrique Cerezo is steadfast.
The Sunday Express says Atletico will not sell for less than €100 million.
For his part, Oblak has intimated he won't seek to force a move away this summer.
