Watford striker Matej Vydra is a target for a number of sides in the Championship - HITC Sport understands from sources close to the club - with the likes of Fulham, Brighton and Reading all in the mix.
Forest's Championship rivals have now been made aware that Vydra could be available and Fulham, Brighton and Reading all are monitoring the player's situation.
Vydra has found himself down the pecking order behind Troy Deeney and Odion Ighalo in Quique Sanchez Flores' plans at Vicarge Road.
Vydra scored 16 goals for Watford last season, but the striker is yet to play a single minute in the Premier League in the current campaign.
The 23-year-old was left out of the squad for last weekend's draw with Southampton and Flores has refused to rule out a move for the player before the transfer window closes.
Fulham, Brighton and Reading are all looking to bring in a striker and are ready to move for Vydra if Watford agree to let him go.
