Port Vale midfielder Chris Lines is a target for Oldham Athletic, Bradford City, Coventry City and Gillingham reports Sky Sports.
Lines has impressed in his first season at Vale Park after arriving on a free transfer from Sheffield Wednesday.
He is one of the Vale players to be offered a new contract by the club during the final week of the season.
The 28-year-old is out-of-contract at Vale Park this summer and is understood to be frustrated that the Valiants haven’t offered him a new contract earlier and has said he would have signed a new deal had it been offered during the season.
The midfielder has scored two goals in 39 appearances for Micky Adams’ side.
