Brentford have submitted a £12m offer for Hull City winger Keane Lewis-Potter who has also attracted interest from West Ham.
Brentford had a bid rejected for the 20-year-old in the summer and have returned after failing to prise Brennan Johnson from Nottingham Forest.
Lewis-Potter has shone in an arduous campaign so far for the Tigers, scoring six goals and laying on another four assists in 29 appearances.
The attacker has also drawn the interest of other Premier League clubs including Tottenham.
Meanwhile, Brentford midfielder Mads Bidstrup, 20, is wanted on loan by Blackburn Rovers.
The Dane has yet to start a Premier League game this season, making just top-flight appearances so far.
He did however register two assists in the FA Cup third round win against Port Vale earlier this month.
