Celtic have added only one new player to their squad this summer, a 24‑year‑old Colombian striker, Camilo Duran, in a deal worth £6 million. The move, announced on 10 July, follows the club’s limited activity in the transfer market and a board‑level acknowledgment of the challenges it faces when competing with English Championship clubs.

Duran, who joined from Azerbaijani side Qarabag after scoring 15 goals last season, will sign a five‑year contract. The club’s official statement said the forward will be available for international clearance before the start of the 2026‑27 season. He is the first proven forward Celtic have purchased since striker Kyogo Furuhashi left for Rennes 18 months ago.

In addition to Duran, Celtic have re‑signed former England midfielder Alex Oxlade‑Chamberlain on a one‑year deal that runs until the summer of 2026, with an option for an extra year. The re‑signing was confirmed on 7 February and was followed by a contract extension on 4 July.

The club’s transfer activity has been hampered by a number of factors. Minutes from a meeting between the board and supporters in Cork, published online, reveal that manager Martin O’Neill told the club that his squad was “in major need of signings” and that it was not strong enough to compete, despite last season’s double. Chief executive Michael Nicholson explained that the club is “slow” because of difficulties dealing with agents and the financial gap between the Scottish Premiership and the Premier League and Championship.

O’Neill also said the club’s focus is on younger players who are attracted by the prospect of European football and a drive to succeed. The board has recently approved a long‑term strategy that aims to make Celtic the best club in Scotland, financially sound and competitive in Europe.

The transfer situation has sparked unrest among supporters. A pre‑season friendly against Middlesbrough on Saturday has been called for a boycott by several supporters’ groups. Chris Sutton, a former Celtic player, warned that the club may need to spend more than £50 million to rebuild the squad and remain competitive in the Champions League.

Celtic’s first match of the 2026‑27 season will be a home league game against Dundee on 3 August at 19:30. The match will be broadcast live on Sky Sports, as will all six top‑flight games that weekend – a first for the network.

The club’s transfer strategy remains uncertain. While Duran and Oxlade‑Chamberlain have joined, there is no sign of an extended deal for Kelechi Iheanacho, whose goals from the bench were vital in the latter stages of last season. O’Neill’s comments suggest that the club will continue to target younger talent, but the financial constraints and competition from English clubs will likely limit the scale of new signings.

Celtic entered the 2025‑26 season as reigning champions and won the Scottish Cup that year, completing a domestic double. The club’s 2026‑27 campaign will be O’Neill’s first full season as manager, and the title defence will test whether the limited transfer activity is sufficient to maintain the club’s domestic dominance and European ambitions.

The situation remains fluid. The club’s board, supporters, and management will need to balance financial prudence with the need to strengthen the squad if Celtic is to continue its success in the Scottish Premiership and on the European stage.
