Noel Whelan has blasted Celtic defender Kristoffer Ajer for instructing his agent to hold negotiations over a potential move this summer.

Speaking exclusively to Football Insider assistant editor Russell Edge, the former Leeds and Aberdeen striker insists the 22-year-old should do his talking out on the pitch rather than through his representatives.

As revealed by Football Insider, the giant Norway international has instructed his agent holds talks with prospective suitors as eyes the exit door at Parkhead.

This site revealed last month that Celtic are preparing for their defensive mainstay to leave after four years at the club.

Whelan has taken aim at Ajer for trying to engineer a move away, insisting he needs to show more respect to a club who have elevated his standing in the game.

Whelan told Football Insider: “It’s frustrating for Celtic that he’s going and saying that. We keep talking about commitment and loyalty, I would much prefer to hear nothing from players, quite frankly.

“I’d rather they get on with their job with the club that they’re contracted to. Whatever happens with that player is down to the club, Celtic, and the offer that comes in from another club.

“I don’t like hearing this from players, asking agents to find out. You’re at a massive football club that have done a lot for you, show some loyalty and respect to the club that’s paying your wages and giving you this opportunity to raise your profile.” 

Ajer, who stands at 6ft 4in, has been a regular for Neil Lennon this season, playing 49 times across all competitions.

He has a total of 129 games under his belt for the Hoops, as well as 14 caps for Norway.

In other Celtic news, Darren Bent has thrown his backing behind the Hoops’ plans to sign an attacking gem from the Premier League.
