Celtic’s summer transfer window saw the club wave goodbye to several key players as the club looked ahead to a new era under veteran boss Martin O’Neill.
Daizen Maeda, Reo Hatate and Arne Engels all left in big-money moves, while fringe men Stephen Welsh, Paulo Bernardo and Maik Nawrocki all departed for pastures new as Celtic’s new-look squad took shape ahead of the 2026/27 campaign.
It started perfectly, with new signings Camilo Duran and Kasper Hogh helping the side record six successive league wins. However, a damaging loss to LASK in the Champions League playoffs, followed by back-to-back defeats against Rangers, has turned the mood sour at Parkhead in recent weeks. But what has happened to those that have left?
Here we look at the 15 Celtic players who moved away from the club before the start of the new campaign, and assess how they have done for their new teams in the opening months of the season. Who has found success away from Parkhead - and who regrets their decision to leave?
