Nigeria defender, William Troost-Ekong had bid goodbye to Watford ahead of his transfer to Serie A club, Salernitana.

The Super Eagles vice-captain penned an emotional farewell to his former teammates, coaches and supporters via the social media on Monday night.
“The moment has come for me to move on from @WatfordFC after 3 special seasons shared with everyone involved. From everyone at the restaurant, security workers, volunteers at the stadium to the medical & office staff and all the rest you have made my time what it was,” Troost-Ekong wrote on his Twitter handle.
“The coaches and most of all my teammates, I can only say thank you!!!
“The Pozzo family for believing in me and the important 5 years of my career at both clubs with the highlight the promotion and a chance to achieve my boyhood dream of playing in the Premier League.
“To all the fans thank you for your support, it has been special going from watching as a boy to stepping on the pitch as a player. As now a fan again I wish for promotion just as much as all of you and will be back watching from the stands in the future.”
The centre-back is returning to Italy after his previous stint with Udinese.
He was at Udinese for two years before joining Wafford in 2020.
