Austrian centre-back Christoph Klarer, who is 25 years old, played in Birmingham's 3-1 defeat to Southampton in December. He was the club's player of the season last year and has made 36 appearances and scored 2 goals in the Championship this term. The centre-back's development at Staplewood aids a potential transfer, and Saints might require one or two new centre-backs if they do not achieve promotion. Klarer joined Birmingham in July 2024 and is under contract until June 2029. His current market value is €7.00m, according to Transfermarkt.
