Several sources: Celtic defender set for Schalke talks
According to reports, Schalke 04 are closing in on Celtic's Christopher Jullien.
Celtic centre-back Christopher Jullien is on his way to Germany to hold talks with Schalke 04, according to Football Scotland, WAZ and Sky Germany.
The 29-year-old is reportedly set to undergo "various medical and athletic tests" in Gelsenkirchen.
Jullien has found himself well down the pecking order at Celtic after recovering from a long-term knee injury and made just one appearance during the 2021/22 season.
He is no stranger to German football, having previously spent two seasons on loan at Freiburg, during which he featured once for the senior side.
Celtic signed Jullien from Toulouse for €8 million in 2019, and he has one year left on his contract.
