Diallang Jaiyesimi became Dean Brennan’s first signing of the 2026 January transfer window on loan from Leyton Orient, who he joined in the summer of 2025.

The 277-year-old has a wealth of experience across the EFL, with 40 goal contributions to his name.

The versatile midfielder began his career at Dulwich Hamlet, before moving to Norwich City where he signed his first professional contract, gaining valuable experience on loan at Grimsby Town and Yeovil Town in League Two as a youngster.

The London-born winger’s first permanent move away from the Canaries came after a successful season with Swindon Town on loan, where he helped the Robins achieve League One status before committing to a permanent deal.

A three-year association with League One side Charlton Athletic followed, where he made a total of 64 appearances for the Addicks and was also loaned out to AFC Wimbledon and St Johnstone in the Scottish Premiership.
