According to the Daily Mail, Celtic are vying with Huddersfield Town over the signature of experienced Millwall defender Alan Dunne.
The Bhoys could be left short in defence this summer if Virgil van Dijk leaves and Jason Denayer heads back to Manchester City after the expiration of his loan deal, so adding depth may be the name of the game for manager Ronny Deila this summer.
Yet, fans may be somewhat surprised to see that it's Millwall's Alan Dunne being linked with a move to Glasgow, rather than a young, up-and-coming player.
Dunne, 32, was born in Dublin but has spent his entire career with Millwall, making over 300 league appearances for the Lions having joined the club 25 years ago.
Millwall look set to be relegated back down to League One after a torrid season at The New Den, and the Daily Mail believe that Dunne is considering his future at the club.
That will reportedly interest Celtic as well as Huddersfield Town, who are allegedly impressed with his competitive nature - despite being red carded ten times in his career.
Dunne can play at right back, centre back or even in midfield, so could be a low-cost, versatile option for Celtic - even if he doesn't grab the headlines ahead of the summer transfer window.
