Proactive rather than reactive has been the way of it under Ange Postecoglou as the Celtic boss has made a habit of jumping rather than waiting to be pushed.
Alistair Johnston was signed as a contingency plan for Josip Juranovic before the Croatian had even decided on his next move while Giorgos Giakoumakis hasn't yet been announced as an Atlanta United player and Hyeongyu Oh has already made his Celtic debut. Contract-wise, his squad is in good shape, with the vast majority of players only arriving within the last few years, but we've already seen signs of his forward planning being applied to tie players down.
Giakoumakis, under contract until 2026, was allowed to leave after talks over a new deal collapsed and the same goes for Juranovic with Postecoglou taking no chances of letting players run their deals down. James Forrest extended his stay until 2025 in the summer and attentions are now likely to turn to three players whose deals, as things stand, are up at the end of next season.
