The 21-year-old, whose contract expires in 2023, is too raw to feature for the first-team but he has outgrown the 2. Bundesliga where he previously played.
It appears that a temporary move is the best solution for the 21-year-old and both clubs. Here's why.
1. No place for Jordi at Arsenal (for now)
Osei-Tutu's natural position is that of a right-back and Arsenal currently have Hector Bellerin – who we believe is not going anywhere despite rumours sending him away from north London – and old-but-fresh signing Cedric Soares will provide competition for the Spaniard.
2. Cardiff is a step forward for Jordi
Last season, the 21-year-old impressed on loan at VfL Bochum in the 2. Bundesliga. Deployed as a right-winger after the resumption of the German season, Osei-Tutu impressed fans with his form, contributing 4 goals and 3 assists in 12 games.
However, the 2. Bundesliga is not as intense as the Championship and playing in the English second division would definitely be a test for the versatile Anglo-Ghanaian.
3. Cardiff's tactics will benefit Osei-Tutu
The Welsh side are managed by head coach Neil Harris, a 43-year-old former striker who enjoys attacking football.
Harris favours a 4-3-3 shape with two wingers. He wants his full-backs to push forward so it's likely that an offensive right-back Osei-Tutu will find it easy to get used to Cardiff's style of play and became a centrepiece at the Bluebirds.
