Manager Rafael Benitez says Newcastle United have not received an approach from Hearts for coach Ian Cathro.
The 30-year-old has been heavily linked with Hearts as the Tynecastle club's current head coach Robbie Neilson nears a move to MK Dons.
Cathro previously worked with Dundee United and Valencia and is now part of Benitez's backroom team at St James' Park.
"Ian is a great coach," said Benitez of the Scot.
"We don't have any official approach. We are happy with him and we will continue with that. He is a young coach, he has some experience and has a great future.
