KARL Robinson has attempted to leave the door ajar for Chris Cadden despite the full back leaving Oxford United yesterday.

The paperwork on the Scot’s recall was completed, after Columbus Crew triggered the recall clause.

A substantial fee remains on the table, but is well short of the MLS club’s £1m asking price for the 23-year-old.

Agreeing a deal now looks a long shot – and United have made significant progress multiple like-for-like targets – but until a replacement is signed Robinson remains keen.

He said: “If he wants to come and sign for us in the next ten days we will sign Chris Cadden.

“The chairman is willing to pay a lot of money for a right back at this level that other teams wouldn’t pay.

“The salary would be fine, the fans love him, the player loves being here.

“They know what our top figure is.

“It’s absolutely crazy. Let’s just get the deal done.”

Cadden has not played for the MLS club, who loaned him out to the U’s immediately after sealing a permanent transfer from Motherwell in July.

The Scotland international chose Ohio for a change of scenery after more than a decade at Fir Park.

Before leaving yesterday he paid his thanks for the last six months.

Cadden told the U’s website: “It’s a brilliant club and I want to thank the gaffer, the players and staff and especially the fans who have been unbelievable ever since I arrived.

“I’m looking forward to my new adventure but I want to wish Oxford the very best for the future.

“The fans deserve success and I believe they have the right people to lead them to that this season.”

Robinson though has questioned the advice Cadden has received and feels moving across the Atlantic at this stage in his career is the wrong move.

He said: “At 23 and going to play in MLS, I don’t get it.

“Bow (Charlton boss Lee Bowyer) got criticised for Joe Aribo going to Glasgow Rangers, but I think this is ten times worse.

“Chris Cadden is a top Championship right back and will grow with this club.

“You don’t know where his end game is, he’s still really young.

“Maybe I’m being harsh, but it’s only because I care for the boy.”

He added: “At no stage do I want anyone to think this is Chris Cadden, because he’s openly said he’d love to stay here.”
