Sky Sports understands Blackpool have had a fresh bid for Southend United's highly-rated Bilel Mohsni rejected.
The Shrimpers have just taken up a year's option on the French stopper, who can also play up front, but they face a fight to keep him.
Seasiders boss Ian Holloway has been tracking Mohsni for over 12 months and has had bids rejected in previous windows, but he is now looking to press through a deal this summer.
Blackpool are understood to have lodged their new bid earlier this month but Southend again rejected their advances.
A number of other Championship clubs, including Middlesbrough, Bolton and Burnley, are also continuing to monitor Mohsni's situation.
