Manchester United are actively seeking a replacement for goalkeeper David de Gea.
The Sun says De Gea has still not signed United's offer of a new deal, worth around 350,000-a-week, despite months of talks.
While the club are still desperate to keep him, insiders believe he will be sold in the next window, to avoid missing out on a hefty fee.
And that has seen them drawing up contingency plans if the long-term stand-off with their Spanish keeper isn't resolved.
Atletico Madrid's Jan Oblak has always been on United's radar and they have continued to monitor him.
But United have also been watching games in Eastern Europe recently, with Dinamo Zagreb No.1 Dominik Livakovic high on their list.
