Brentford have set out their asking price for Romaine Sawyers after rejecting a bid from Celtic, report The Scottish Sun.
Celtic boss Neil Lennon is believed to be keen on the 27-year-old, and it is believed the club will make an improved offer for Sawyers, but it is not yet clear if they will meet his asking price.
With Stoke also reportedly interested, The Hoops may have to act decisively and match his valuation or risk losing out on him.
Sawyers has become an important player at Brentford over the last three seasons, making over 40 appearances each year, whilst contributing a total of eight goals and 20 assists.
Brentford are right to state their asking price and stick to it, and with more than one club interested they are in a good position to negotiate a higher fee or possible clauses if they wish.
Sawyers is a good player and £2.5m is a reasonable valuation, despite the fact he has improved since joining and could be about to reach his peak.
The Bees could use the money to bring in someone more productive, and if they are aiming for the Premier League they will need players who will be able to cut it in the top-tier, which Sawyers would likely struggle to do.
