Defender Kristoffer Ajer has committed his future to Brentford.

The Norway international has signed a new deal which runs until the summer of 2028; the club has an option to extend Ajer’s contract by an additional 12 months.

Ajer made his 50th appearance for the Bees before the international break.

He has played 12 games in all competitions this season and assisted Bryan Mbeumo during Brentford’s 3-0 victory over Fulham in August, charging forward from deep inside his own half to tee up the final goal of a pulsating west London derby.

“I’m very pleased that Kristoffer has extended his contract,” said Brentford head coach Thomas Frank.

“During his first two seasons with us, he was very unlucky with injuries; he never got that rhythm or run of games.

“Now he is playing regularly at centre-back and right full-back and I think he plays both of those positions at a very high level.

“Kristoffer has shown consistency and quality in this recent block of games, which I’m pleased about.

“He has made good improvement in his aerial ability in both boxes, and we know he has great quality on the ball. He is so quick to recover during defensive transitions.

“Kristoffer is getting better and better. He is working hard to realise his potential and we are excited that he will take those next steps with us.”

Ajer, who began his professional career in Norway with IK Start, joined Brentford from Celtic in July 2021.

He collected a series of trophies during his five years in Scotland. Celtic won the domestic treble in three consecutive seasons: 2017/18, 2018/19 and 2019/20. Ajer was named in the Scottish Premiership PFA Team of the Season in the middle campaign. In total, he played 176 games and scored seven goals for Celtic.

Ajer made his first appearances for Norway at under-15 level and worked his way through the age groups. He made his full international debut before his 20th birthday and has 33 caps to date.
