Rangers have been told their pre-contract offer for Alfie Doughty is destined to fail – as he has agreed terms with Stoke City.

The runaway Scottish Premiership leaders and Celtic have both lodged offers for the versatile Charlton Athletic defender, 21, as they look to land him on a cut-price summer deal.

But Stoke are closing in on the signature of Doughty after their £650,000 bid was accepted by the Addicks.

Ibrox sources have told Football Insider that Rangers chiefs have been told that Doughty has agreed terms in principle with Stoke.

Michael O’Neill’s side are set to sign the left footer, who can play at left-back or left midfield, on a buy-to-loan deal.

It would see him pen a long-term contract with Stoke before heading back to Charlton on loan for the rest of the season.

Rangers have targeted a number of potential pre-contract deals this month, with the likes of Preston North End duo Ben Davies and Daniel Johnson also on their radar.
