Seriki came to the Blades in 2019 after a spell in Bury's academy.

After a year in the U18s, he became a huge part of Paul Heckingbottom's U21s that won the PDL North title before heading out on several loan spells, including Beerschot in Belgium.

After making his first team debut in the Premier League against Newcastle United, Seriki went out on loan to Rochdale last season and made 24 league appearances.
