Watford have re-affirmed their winger Ismaila Sarr is injured after Senegal accused the club of refusing to release him for the Africa Cup of Nations.
The 23-year-old has been out with knee ligament damage since November.
The tournament starts on 9 January and Senegal named Sarr in their squad.
In a statement, the Senegal Football Federation claimed the Hornets had "blocked" Sarr from joining the team after he had "expressed his desire" to feature.
The Federation said: "The FSF wishes to express its deep condemnation of the disrespectful, pernicious and discriminatory behaviour of Watford who seek by all means to prevent a player from playing with his national team.
