Watford have confirmed that former Cameroon international Nicolas Nkoulou is leaving the club.
The centre-back is not among the players that the Hornets will entrust to get them back into the Premier League.
Following relegation to the Championship, Watford are letting several players leave on free transfers.
"Following the conclusion of the 2021/22 Premier League season, Watford FC can confirm that five first-team players have left the club," part of a statement on the club website read.
"Defender Nicolas Nkoulou – who made three league appearances after signing in October 2021 – and forward Andre Gray – who spent the last campaign on loan at Queens Park Rangers – have also departed upon the expiration of their deals.
"We thank the departing players for their contributions and wish them the best of luck for the next steps in their careers."
