Brentford’s Danish defender Luka Racic has agreed a four-year deal to stay at the club until 2023.
The 20-year-old centre-back played in the first four games of the season, but has since been kept out by injury.
Racic, who joined Brentford’s B team from FC Copenhagen just over a year ago, has also been officially promoted to the senior squad.
“He is a very aggressive defender but also a clever defender and skilful with the ball,” said boss Thomas Frank.
“We have big belief in him and feel he has a very bright future.”
Racic follows Patrik Gunnarsson and Jan Zamburek as the third player to step up to the senior squad from the B team this season.
