Fulham are reported to have made Manchester United an offer for midfielder Ryan Tunnicliffe, who is currently due to stay on loan with the Blues until the end of the season.
According to Sky Sports, the Cottagers have made a joint bid for Tunnicliffe and another midfielder Larnell Cole, both of whom manager René Meulensteen will know well from his time as assistant boss at Old Trafford under Sir Alex Ferguson.
Tunnicliffe has been a regular in the Town side since joining on loan in August, making 24 starts and five sub appearances. He extended his spell until the end of the season earlier this month.
Losing the 21-year-old former England U17 international would be a blow for the Blues, although they are already reported to be talking to a potential replacement, Leeds midfielder Paul Green.
Meanwhile, Saturday's opponents Bolton are understood to have made an enquiry to Millwall regarding ex-Town midfielder Liam Trotter.
The Lions themselves, along with Burnley, are talking to Yeovil about another member of Town's 2005 FA Youth Cup squad, winning goalscorer Ed Upson.
Another member of that team, striker Danny Haynes, completed a move from Notts County to Hibernian yesterday, while former defender Mark Venus has applied for the vacant Shrewsbury manager's job.
