Sky Sports understands Peterborough have made a bid for Southend winger Ryan Hall.
Hall impressed at Roots Hall last season, netting 14 goals and 25 assists in all competitions, and his assist return was the highest by any player in all leagues in England.
The former Crystal Palace man's showings have attracted interest from a host of Championship clubs and Peterborough have made a firm offer for Hall.
Posh boss Darren Ferguson is keen to add to his attacking options and is a big fan of Hall.
Hall is in the final year of his contract and Southend are reluctant to lose last season's top scorer.
