The centre-back is in his second spell at the club, having rejoined on a permanent deal in September 2024 after a previous loan stay the season before. 

The 6ft 3in centre-back joined the Huddersfield academy ranks from Kent Football United in 2018 where he went on to feature for the U17s, U19s and U21s. His first senior football experience came in spells in the Northern Premier League with Tadcaster Albion and then a further seven appearances for Welling United in the National League South. 

Olagunju then went on to make six EFL appearances for Port Vale on loan in 2021, adding another League Two outing with Crawley Town. In his first spell with the Fleet, from October 2023 to January 2024 he impressed in clocking up nine appearances before returning last season following his release by Huddersfield.

He featured 32 times in the 2024/25 campaign as well as playing for Hemel Hempstead Town during a loan spell.
