Manchester United are reportedly open to making a big-money approach for Atletico Madrid goalkeeper Jan Oblak.

With the performances of David de Gea coming under increasing scrutiny, United may potentially consider finding a replacement for their long-time number one.

Although Dean Henderson could be promoted into the starting lineup, The Sun claims that United want to be informed of any developments involving Oblak.

The Slovenia international has recently been linked with a switch to Chelsea, who are eager to bring in an alternative to Kepa Arrizabalaga.

However, with Atletico showing little interest in a part-exchange deal, it remains to be seen whether the Blues are willing to get anywhere near to Oblak's £109m release clause.

While Oblak still has three years left on his contract, a significant bid may tempt Atletico into a sale this summer.
