The deal taking the Toulouse defender to Celtic Park is reportedly worth up to £8million

Celtic have reportedly reached an agreement to sign Toulouse defender Christopher Jullien.

The centre-back has attracted interest from Spain, England and Germany, but the Scottish Premiership club appear to have won the race for his signature.

L’Equipe report that the 26-year-old has held extensive discussions with the Hoops and is expected to undergo a medical in the next 48 hours.

The Daily Record claim a deal for Jullien has been struck between the two clubs worth up to £8million.

Neil Lennon has been in Paris to try and complete the deal for the former France youth international, with Jullien in line to become Celtic’s first signing of the summer.

Jullien enjoyed spells with Auxerre, SC Freiburg and Dijon before joining Toulouse in 2016.

The defender has previously been linked with a move to the Premier League and reportedly wanted to join former team-mate Issa Diop, who plays for West Ham, in England’s top flight.

In May, he said: “I saw him (Diop) again recently. He spoke to me about a lot of things, like his adventure, how things were over there.

“It’s true that it’s enticing and it makes you want it. We know the Premier League is a super impressive league.

“He’s convinced I’ll be joining him there soon but, as I said, I’m still at Toulouse and we’ll see about the future.”

That move to the Premier League is on hold for now, however, as it looks like Jullien will be playing in the Scottish Premiership next season.
