Christian joined the Club on loan from Brighton & Hove Albion in August 2021, before making his move to Portman Road a permanent one the following January. 

The Cornwall-born goalkeeper quickly established himself in the first-team during his first season at Portman Road, before going on to start all 46 league games as Town won promotion to the Championship in 2022/23. 

He played behind a defence which kept 23 clean sheets in League One, earning him the second Golden Glove of his career, having previously done so while with former club Wigan Athletic. 

A foot injury in July of 2023 saw Christian miss the start of the new season but he continued to be an extremely valuable member of the squad, appearing in the promotion-clinching victory over Huddersfield which secured promotion to the Premier League for Town in May 2024.

Following the start of the 2024/25 season Christian put pen to paper on a new two-year deal at the Club, extending his stay at Portman Road until the summer of 2026.

As well as the Latics, Christian has previously spent time with Bury, Luton, Southend, and Blackburn on loan from Brighton, having originally joined Albion from boyhood club Plymouth after coming through the Argyle youth system. 

He has represented England at U19, U20 and U21 level, and wears the number 28 shirt for Town.
