Wolves boss Nuno is being linked with Maurizio Sarri's job at Chelsea.
The Daily Star says Chelsea's mini-revival still hasn't convinced the hierarchy, who have put Nuno high on their list of managerial targets.
The 45-year-old has earned rave reviews at Wolves this season, with his team playing an entertaining, free-flowing style of football.
It has been claimed that Chelsea have been seriously impressed with the former Porto goalkeeper - who was part of their 2004 Champions League-winning side.
Wolves are currently in the mix for a Europa League spot as they sit seventh in the table.
