Watford have terminated the contract of defender Sebastian Prödl by mutual consent.
The 32-year-old Austrian, who was voted Player of the Season in 2016/17, made 85 appearances in his time at Vicarage Road.
“It was always a dream to play in the Premier League and Watford gave me this opportunity," said Prödl.
“I will always reflect very positively on my time here. When I signed four and a half years ago, my gut told me it was going to be a very good move and everything has proved this to be right.
“I am just grateful to have Watford on my CV, I am moving on now but I am glad I have been here.
“Being voted Player of the Season as a defender was a special honour. Big thanks to all the supporters for always believing in me, even when I wasn't playing.
“I will always come back and watch the guys play at Vicarage Road and Watford will always have a place in my heart."
