Rotherham United striker Alex Revell could reportedly leave the Millers after failing to agree a new contract with the club.
Revell netted twice to help Rotherham fight back from 2-0 behind to overcome Leyton Orient in the League One playoff final in May, but the 31-year-old has been unable to agree terms over a fresh deal at the New York Stadium.
According to Sky Sports News, that has alerted a number of clubs in the Football League, with Birmingham City said to be eager to make Revell their ninth summer signing.
League One teams Sheffield United, Coventry City and Bristol City are also believed to be interested in acquiring the forward, who netted 13 times last season.
