Blackpool have had a fresh bid for Barnet starlet Albert Adomah turned down, skysports.com understands.
Forward Adomah is attracting huge interest with Premier League, Championship and League One clubs keen on landing the 21-year-old.
Norwich and Blackpool both had bids turned down earlier this summer and now Ian Holloway has returned to Underhill with a new offer.
It is believed the fresh bid was for around £200,000, but Barnet have rejected this latest approach.
The Bees are keen to keep hold of their prized asset but could face a big battle to hang onto him before Tuesday's deadline closes.
