Cardiff City have completed the permanent signing of Nigeria Under-21 international Semi Ajayi from Arsenal.
The 21-year-old has made the switch to the Welsh capital after spending the final two months of last season on loan with the Bluebirds.
He didn't appear for the Cardiff first team, but featured four times for their Under-21 outfit, scoring a brace on his debut.
He has now put pen to paper on a two-year contract with the Championship side.
