'I follow Saudi football and this is what I think of Matthias Jaissle being Newcastle manager'

Matthias Jaissle will find it "really difficult" to "hit the ground" running if he becomes the next Newcastle United manager.

That is according to former Everton chief executive Keith Wyness, speaking exclusively to Football Insider, who believes that the German is about to enter a "whole new level" of football if he moves to St James' Park.

This comes amid news of Eddie Howe's resignation, with PIF already in advanced talks over a move to appoint Al Ahli boss Jaissle as his successor.

The 38-year-old has secured back-to-back Asian Champions League titles with the Saudi Arabian outfit, but has never managed a club in one of Europe's big five leagues.

Jaissle's only previous senior managerial experience has come with Red Bull Salzburg, and previously their reserve team FC Liefering.

Wyness has been impressed by the German's exploits in the Middle East, but has warned that it will be a huge jump up to the Premier League.

Matthias Jaissle to face behind the scenes issues

Everton’s former chief Wyness – who served as CEO at Goodison Park between 2004 and 2009 and now runs a football consultancy advising elite clubs – believes that the lack of stability at Newcastle behind the scenes will make life difficult for Jaissle.

The ownership have been working on his arrival at St James' for several weeks, but Wyness does not expect a smooth transition period after the end of the Howe era.

"I've followed Saudi football for a while now, and he (Jaissle) has certainly done well there," he said.

"His previous record is good, but nothing’s quite as big as the North East, and the passion of the Geordie fans.

"It’s a whole new area for him, and a whole different level. Without a settled top-level within the club, it’s going to be really difficult to hit the ground running."

PIF walking 'tightrope' at Newcastle

Wyness told Football Insider earlier in July that PIF are walking a "tightrope" at Newcastle at the moment.

The Scottish businessman made it clear that "tensions" are high between the supporters and the club hierarchy of late, and another round of big-name sales has only exacerbated that further.

Wyness believes that the supporters' ambitions face a conflict of interest with the ownership's desire to take their time and make measured decisions.

With a new boss coming in who is relatively unproven in European football, the pressure will undoubtedly be on him from the very beginning.
