Celtic only have 'one option' as true cost of Ajer deal revealed - Kieran Maguire

Celtic beancounters would normally be able to relax after sanctioning a big-money sale – but now they must reinvest in the transfer market.

So says finance expert Kieran Maguire, speaking exclusively to Football Insider after Celtic confirmed the sale of Kristoffer Ajer on 21st July.

This site revealed earlier that day that the 23-year-old defender had passed a medical and was set to join Brentford in a £13.5million switch.

The deal, which includes over £4m in add-ons, is Celtic’s fourth eight-figure sale in as many seasons.

Jeremie Frimpong (£11.5m), Kieran Tierney (£25m) and Moussa Dembele (£19.7m) have been among the headline departures in recent years.

But Maguire asserts that the Hoops must re-funnel cash from Ajer’s sale into the transfer budget if they want to be competitive in 2021-22.

“The good thing is they have the cash in the bank,” he told Football Insider correspondent Adam Williams.

“As we know, Celtic’s model has generally been to sell one big-name player for an eight-figure fee per year. That’s how they manage to stay sustainable.

“If you are selling from a position of strength, that shouldn’t be a problem. But this time it’s different. I don’t think Celtic are selling from a position of strength at the moment.

“The fans will, therefore, be hoping that the money they received from the sale will be reinvested in the squad. That’s the only option they have if they want to be competitive”

Ajer featured 176 times for Celtic before joining Premier League new boys Brentford.

He signed for the club as a free agent in 2016.
