Manchester United are reportedly exploring the prospect of making a move for Atletico Madrid goalkeeper Jan Oblak, should David de Gea move to Real Madrid.

Real could soon step up their interest in De Gea following the announcement that number one keeper Iker Casillas will soon be moving to Porto, and AS now suggests that United could look towards Atleti's 22-year-old stopper as a replacement.

The same report states that Atletico would only be willing to sell if United were able to meet the youngster's buy-out clause, which is set at around £32m.

Oblak joined Madrid from Benfica at the start of last season and impressed during his debut campaign in La Liga.
