Celtic have agreed a fee with Toulouse for centre-back Christopher Jullien.
Record Sport exclusively revealed earlier in June the towering defender had emerged as a top target for boss Neil Lennon.
The Hoops boss was in Paris this week as the club sought to tie up a deal for the former France U-20 international.
And it's understood an agreement has been struck with Jullien now set to thrash out personal terms with the Premiership champions.
Jullien has attracted interest from clubs in England and Germany but Celtic have moved quickest in the race to sign him.
The 26-year-old - who has also had spells at Auxerre, Freiburg and Dijon - sparked transfer speculation earlier on Tuesday as he posted a cryptic photo on Instagram boarding a plane.
He's now set to provide a boost to Lennon's backline after Dedryck Boyata's departure and lingering uncertainty over the potential loan return of Filip Benkovic.
Reports in France claim Jullien is keen on a move to Scotland.
Meanwhile, David Turnbull 's move to Parkhead hangs in the balance after issues arose during the midfielder's medical.
Parkhead bosses are now back in talks with the player and Motherwell to work out the best course of action for the 19-year-old.
Turnbull finally looked set to seal a move to Parkhead after turning his back on a switch to Norwich City in the signing story of the summer so far.
He was due to join Neil Lennon's squad at their pre-season training camp in Austria but the transfer has now been thrown back into uncertainty.
