Christopher Jullien has opened up on his 'complicated' relationship with Ange Postecoglou as he made reference to Celtic's tactical approach as being like a game of chess.
The £7million signing under Neil Lennon from Toulouse made his return to France with Montpellier during the summer after failing to re-establish himself in the Hoops' backline following a lengthy spell on the sidelines. Recruits Cameron Carter-Vickers and Carl Starfelt formed a solid duo and chances became slimmer and slimmer.
Stephen Welsh and newest addition Moritz Jenz then jumped ahead of the Frenchman in the pecking order and he knew his time was up as he opened up on his lessons off the park as he learned much more about himself. Despite his lack of minutes on the park, the stopper admits to learning lots tactically off Postecoglou and that has made him become more 'tactically savvy'. The 29-year-old delivered a behind-the-scenes analysis of Angeball as he discussed his exit from Parkhead.
