Leeds United have made an approach to sign Newcastle United goalkeeper Karl Darlow before the window shuts next month, Football Insider can reveal.

The Yorkshire giants are laying the groundwork for a late keeper signing amid doubts over the futures of current senior pair Kiko Casilla and Bailey Peacock-Farrell.

A Leeds source has told Football Insider that the club have registered their interest in Darlow and the viability of a loan or a permanent deal.

The 28-year-old has entered the final year of his contract with Newcastle and is keen to secure regular football after making just a single appearance for the club last season.

The ex-Nottingham Forest keeper, who stands at 6ft 3in, is behind established number one Martin Dubravka in the St James’ Park pecking order and that is unlikely to change as a result of Steve Bruce’s appointment.

United have reignited their interest in Newcastle goalkeeper Karl Darlow after placing him high on their shortlist of targets to potentially replace Casilla.

They looked closely at signing him in January but ex-manager Rafael Benitez was unwilling to offload him at the midway point of the season.
