"We have had expressions of interest in Sean Gregan from a number of clubs," read a statement from West Brom. "But none of their offers have matched the valuation of Sean that our club feels is appropriate, either in respect of his abilities as a player or in respect of his leadership qualities."
Gregan is thought to be keen to leave to secure regular first team football, and Leeds are expected to make a further offer although they face competition from other clubs.
The 30-year-old seems to favour a move north, and Leeds' offer is believed to have add-ons, rather than being a one-off payment.
