Newcastle United's search for a permanent successor to Alan Pardew has stalled after Remi Garde and Frank de Boer were both distanced from the position at St James' Park.

John Carver has been installed until the end of the season but the club are expected to make an external appointment ahead of the 2015-16 campaign after Pardew left for Crystal Palace in January.

Both Garde and De Boer were among the leading candidates for the role at Newcastle however both have separately been all but ruled out of taking over at the north-east club.

Since leaving Lyon in the summer of 2014 for personal reasons, Garde has taken a 12-month leave of absence from the game but he has yet to decide when he will return to management.

Questioned on a potential move to the Premier League, Garde said: "I have a duty of confidentiality in this matter to Newcastle then I'll be very honest and very integrated with respect to the leaders of Newcastle, I cannot say more."

"I cannot say I'm desperate to return on a bench, far from it. But I can easily say that I loved this coaching experience. I needed to recover and rejuvenate myself. But I had probably caught a virus to start this profession.

"I do not close the door to anything or to take another year off, or, to dive into a project that would suit me."

And now De Boer has become the latest manager to be ruled out of a move to Newcastle after his brother, Ronald, stated he was "90%" certain to remain at Ajax.

De Boer's future has been the source of constant speculation, though, with the Amsterdam-based club trailing Eredivisie leaders PSV Eindhoven by 14 points, and the former Netherlands captain looks likely to stay on and reassert Ajax's dominance.

"I'm 90% certain he will stay at Ajax," Ronald told Talksport. "It all depends on what club is coming to ask him to continue coaching them.

"It all depends which club comes for him. It is very important to Frank but he doesn't have to go as he's very happy at Ajax."
