Skysports.com understands a number of sides are tracking Millwall midfielder Liam Trotter.
Trotter has enjoyed a fine season for Millwall and his performances have not gone unnoticed.
The likes of Wigan, Norwich and Nottingham Forest are all thought to be admirers of Trotter after watching him in action this season.
The 22-year-old is highly regarded at Millwall and he was rewarded with a new deal in January.
Trotter popped up with eight goals from midfield this season and Millwall would be loath to lose the former Ipswich man.
