Former Brentford midfielder Adam Forshaw is the subject of transfer interest from Leeds and Cardiff City.
The Middlebrough man has been a peripheral figure for the Tees-siders this season, making just 14 appearances in all competitions and hasn't featured since December 9.
Boro want £2.5million for the out-of-favour midfielder as they look to recoup what they originally splashed out on him in January 2015.
The former Everton trainee spent two full seasons at Griffin Park, signing for the club in May 2012 after a loan spell.
He made 82 Brentford appearances in League One after signing permanently, scoring 11 goals, as he helped the Bees end their 21-year exile from the top two divisions in 2014.
He left for Wigan in the summer of 2014 before moving to Middlesbrough in January. He's made 92 league appearances for Boro, scoring twice.
