Atletico Madrid goalkeeper Jan Oblak is monitoring David de Gea's situation at Manchester United.

ESPN says Oblak wants to quit the Spanish club to become De Gea's replacement at United.

The Slovenian - who was seemingly a United fan in his youth - has become increasingly frustrated at the transfer activity at the Wanda Metropolitano this summer, as he's seen Diego Simeone's side become weaker.

Star forward Antoine Griezmann has announced his intention to leave the club, and is widely expected to join Barcelona.

But Atletico are also losing veteran defenders Diego Godin, Juanfran and Filipe Luis, as well as young talent Lucas Hernandez to German giants Bayern Munich for a club record fee.

Oblak is said to be disappointed with the departures as he feels that they indicate a lack of competitiveness at the club, something which he had been assured against earlier this year when he signed a new deal in the Spanish capital until 2023.
