West Brom have made a bid of about £10m for Hull's Jake Livermore after missing out on Morgan Schneiderlin.
Baggies head coach Tony Pulis is desperate to strengthen his squad this month to build on an encouraging first part of the Premier League season.
Midfielder Livermore, 27, joined Hull in an £8m deal from Tottenham in 2014.
Pulis is a long-time admirer of Livermore and tried to sign him when he was Palace manager.
He is understood to be encouraged that Livermore only made the bench for Hull's victory over Bournemouth on Saturday.
