Arsenal defender Semi Ajayi has completed a loan move to Cardiff City until the end of the season.
The 21-year-old is yet to make a senior appearance for the Gunners, but he has been involved in their matchday squads for a number of Premier League fixtures.
However, he has made 10 appearances for the club's youth team in this season's Barclays Under-21 Premier League.
Ajayi, who joined Arsenal from Charlton Athletic in 2013, has also represented Nigeria at Under-21 level.
