Watford are considering bids for defender Ryan Andrews as the summer transfer window nears its end, but no club has yet met their valuation.
Assistant sporting director Valon Behrami has also indicated that midfielders Tom Dele-Bashiru and Tom Ince could also be leaving Vicarage Road.
Andrews, 21, has made 86 league appearances for The Hornets, the most recent against Swansea City last Saturday when he was sent on as a 78th-minute substitute.
"We've had a few offers for Andrews, for example, and it's something we will take in consideration," Behrami told BBC Three Counties Radio.
