Birmingham have rejected an offer for Tom Adeyemi from an "unnamed Championship club" after the midfielder handed in a transfer request.

Despite being named as Blues' vice-captain by manager Lee Clark ahead of the upcoming campaign, 22-year-old Adeyemi has been linked with a move to Cardiff.

Having come through the ranks at hometown club Norwich and spending time on loan at Bradford, Oldham and Brentford, Adeyemi joined Birmingham last summer and featured in 40 games in all competitions in his first season at St Andrews.

"A formal offer from an unnamed Sky Bet Championship club for the 22-year-old has today (Tuesday) been rejected," said a statement on City's website.

"The club will now meet with the player's representatives to discuss the transfer request further. The club has no further comment to make."
