Nigerian trio of William Troost-Ekong, Emmanuel Dennis and Samuel Kalu will be playing in the English Championship next season, after Watford were officially relegated from the Premier League on Saturday.
Watford’s relegation was confirmed after they lost 1-0 away to Crystal Palace, thanks to a Wilfried Zaha first half penalty.
The Hornets were reduced to 10 men following the sending off of Hassane Kamara for a second bookable offense.
Watford only gained promotion to the English topflight last season and have now suffered the drop with Norwich.
Palace opened the scoring in the 31st through Zaha after Kamara was penalized for handball.
Watford, who suffered their sixth consecutive defeat on Saturday, stay in 19th place on 22 points after 35 games played.
