Watford are likely to complete a double transfer today, having signed Belgian defender Christian Kabasele and close to signing Granada forward Isaac Success.
Kabasele who is part of Belgium's squad for Euro 2016 has signed on a 5-year deal on an undisclosed fee.
Success will sign on a 5-year contract from Granada.
“Today is a bittersweet day for me, because through this letter, I want to say goodbye to the best fans that you can have, of my colleagues, of all workers in the club who have both supported me since I arrived in Granada, in addition to this city that has given me everything,” Success wrote to supporters.
“Now I begin another professional stage, which would not have been possible without my learning and development in Granada.”
