Watford have signed Netherlands defender Daryl Janmaat from Newcastle United, the Premier League club announced on Wednesday.

Janmaat agreed a four-year contract with the Hornets, who are reported to have paid a fee of £7.5 million ($9.9 million, 8.8 million euros) as he returns to the Premier League following Newcastle's relegation last season.

The 27-year-old right-back, who joined Newcastle in 2014 from Feyenoord, admitted he was delighted to be back in the top flight.

"I'm really happy to be here, it's a new adventure for me. I was really pleased that Watford showed interest in me because I wanted to play in the Premier League," Janmaat told Watford's website.

"We (Newcastle) lost three times to Watford last season. They had a good season and I hope we can do the same again this year.

"The club is showing great ambition and wants to improve and I want to be part of that."

Janmaat made 77 appearances in all competitions for Newcastle, scoring four goals.
