Kristoffer Ajer, born on 17 April 1998 in Norway, is a central defender at Brentford FC. Standing tall at 6ft 5in (1.96m) and weighing 13st 3lb (84kg), he sports the number 20 jersey. Aside from his role at Brentford, Ajer has also donned the colours of the Norway national team.
Approximately worth £13.5m in the current market, according to Transfermarkt, Ajer has nearly four years remaining on his contract with Brentford, set to conclude on June 30, 2028.
The 2024 - 2025 season has so far seen Ajer play one Premier League match for Brentford, featuring from the start. He also participated in the 2023 - 2024 FA Cup for Brentford with one start, and in the 2022 - 2024 Euro Qualifiers for Norway where he made three starts and one substitute appearance.
Ajer's professional journey began in 2014 when he joined Start, a club in Norway's OBOS-ligaen, as a trainee. In his debut season, he made 13 first team appearances and scored one goal. The 2015 season saw him play 28 times and net eight goals. His participation waned in the 2016 season, featuring just 11 times but with no goals to his name.
In July 2016, the towering Norweigan said his goodbyes to Start and made the journey to Scottish side Celtic, the signing sealed for around £750k. It was at Celtic that Ajer honed his craft and blossomed into a true professional. His tenure was marked by a steady increase in his participation, eventually cementing his place in the starting lineup. During his time, he made an impressive number of appearances and chipped in with a handful of goals too.
A brief spell away from Celtic saw Ajer transferred to Kilmarnock in January 2017 on loan. He chalked up 16 first team appearances in the Premiership for Kilmarnock before returning to Celtic later that summer.
Post his return, Ajer featured regularly for Celtic, and contributing goals from the back. His development as a steadfast defender continued under the hoops.
The summer of 2021 marked the end of Ajer's Celtic era, as he was transferred to Brentford in the Premier League for a fee of around £14m. Ajer has since given his best in the Brentford jersey, clocking a decent number of first-team appearances and scoring occasional goals. In the ongoing 2024 - 2025 season, he has so far started in one league match alone.
