Christopher Jullien in Celtic transfer clue as he nails his colours to the mast during fitness reminder

Out of favour Christopher Jullien has offered a hint at his commitment to Celtic ahead of pre-season training.

The Frenchman has previously stated he has been fit since January after spending 13 months on the sidelines with cruciate ligament damage.

But that didn't convince Ange Postecoglou to give him game time during the Scottish Premiership run-in with Carl Starfelt and Cameron Carter-Vickers his first-choice centre-back pairing.

The £7m defender has managed just 16 minutes of game time under the Australian, during a Scottish Cup cameo in the rout of Raith Rovers.

With a year left on the 29-year-old's contract, speculation has ramped up over a potential move away from the Scottish Premiership this summer.

However, Jullien appears to have nailed his colours to the mast as he looks to prove he is ready for first-team action.

The defender posted a clip to his Instagram wearing Celtic training gear as he got to work ahead of pre-season training.

Jullien was a big money signing from Toulouse three years ago and was an almost ever-present as the Hoops won the treble in his first season.

Since then his career stalled after a painful collision with a post in a 3-0 win over Dundee United at Parkhead in December 2020.
