Republic of Ireland international Scott Hogan joined Blues during the January 2020 transfer window on loan from Aston Villa until the end of the 2019/20 campaign.
The striker had previously been loan at Stoke City but that agreement was cancelled in order for him to come to Blues.
Hogan made his name at Brentford between 2014 - 2017, scoring 21 times in 36 appearances.
That earned him a big money move to Villa. He has 10 goals from 61 appearances for Villa and was loaned out to help Sheffield United clinch promotion at the back end of last season.
Hogan, scored in a 2-0 win against Ipswich Town at Bramall Lane in April which effectively sealed top-flight football for the Blades.
From Salford, Hogan made his way via the non-league ranks before signing as a professional for Rochdale - the club that released him after coming through their youth system - in 2013.
On the back of his 19 goals in 40 games, Rochdale gained automatic promotion to League One in 2013-14.
From there it was on to Brentford, where he impressed during two-and-a-half seasons.
Hogan has been capped eight times by Ireland.
