Celtic appear to be closing in on another summer signing but it could spell the end for one mainstay at Parkhead...

What's the word?

According to Record Sport, the Scottish champions are on the verge of agreeing on a deal to sign Brighton centre-back Shane Duffy on a one-year loan.

It's claimed that Celtic will pay £2m to sign the 28-year-old for the season and will also pay the majority of his £40k-per-week wages.

The Hoops have beaten off West Ham and West Brom with the Seagulls man expected to be in Glasgow on Tuesday to iron out the final details.

Life after Ajer?

This comes amidst the uncertain future of Kristoffer Ajer after his representatives reportedly asked the club for a valuation on the Norwegian ahead of a potential move away from Celtic Park before the transfer window drawing to a close in October.

He's been linked with a stunning move to Serie A giants AC Milan in recent months.

Duffy would seem like the ideal replacement - standing at 6 foot 4 inches in height, the Irishman has been capped over 33 times and has featured in 96 Premier League matches over the course of his career.

Graham Potter claims the veteran has "been fantastic for me and he has been great in the group" and that's not the first time having described him as "first class" earlier in the campaign despite a lack of regular game time.

The 28-year-old, valued at £8.55m, is an old-school no-nonsense type who has averaged 8.1 clearances per game over the course of his career as per WhoScored.

Ajer alongside Christoper Jullien kept a clean sheet against Well at the weekend but adding Duffy to the equation will certainly give Lennon a nice headache in terms of team selection.
