The prospective appointment of Fergal Harkin as director of football is an exciting first step ahead of a “massive shakeup” at Celtic.

That is the view of former Aberdeen striker Noel Whelan who, speaking exclusively to Football Insider, insisted the Bhoys need to make significant changes behind the scenes.

As revealed by Football Insider on Saturday, a deal for Manchester City transfer guru Harkin is now “90 per cent done” after talks last week.

Celtic opened discussions with Manchester City’s current football partnership manager earlier this month.

His arrival could trigger a complete overhaul of the recruitment team, with further arrivals expected from the Premier League giants.

Celtic’s transfer policy has come under heavy fire this season after the likes of Albian Ajeti and Vasilis Barkas flopped.

David Turnbull is the only notable success story in a season that saw Rangers dominate the Premiership title race.

As such, Whelan has insisted Harkin is the sort of figure Celtic need to lead them in a “different direction”.

Whelan told Football Insider assistant editor Russell Edge: “We talked about them needing to go in a different direction and this is a step forward into doing that so.

“There’s going to be a massive shakeup and changes at Celtic. They have been needed and the freshen up is starting now.

“I think when you’re getting integration with teams like Man City, it can only be beneficial.

“These are the steps that Celtic need to take after the disastrous season that they’ve had. We know what it’s been like on the field.

“Off the field, in the board, in the club, changes have to be made.

“You’ve got to keep up with the Joneses and find ways how to improve your franchise. That’s what they’re trying to do.”

Football Insider revealed last month that head of recruitment Gary Penrice is set to leave Celtic this summer.

In addition, head of football operations Nicky Hammond is also likely to depart Parkhead.
