Coventry's Adam Armstrong and Southend United's Ryan Leonard in action
Sheffield United and Millwall have had bids rejected for Southend midfielder Ryan Leonard, HITC Sport understands from sources close to the club.
Newly promoted Championship duo Sheffield United and Millwall are keen to lure Leonard away from Roots Hall, but Southend have so far rejected their advances.
Southend took up the option to extend Leonard's contract at the end of the season, but they risk losing the player for free next summer if they decide not to sell him this summer.
Southend's Ryan Leonard
Leonard is regarded as one of the most consistent performers in League One after impressing at Southend since his arrival from Plymouth Argyle in 2011.
The 25-year-old as played 236 matches for Southend and he was instrumental in them finishing in seventh spot in League One this season.
Leonard is understood to be keen on a move away from Southend this summer as he wants to play at the highest level possible and hopes the club will not stand in his way of playing in the Championship.
Sheffield United and Millwall both remain keen on Leonard and are expected to come back with new improved bids for the midfielder as they look to persuade Southend to sell their prize asset.
