Watford, a Sky Bet Championship team, did not include forward Emmanuel Dennis in their preseason trip to Austria.
Following the club’s relegation from the Premier League the previous season, Dennis has been linked with a move away from the organization.
The Nigerian international player made 33 appearances for the Hornets in the league and scored 10 goals while also dishing out six assists.
The London club has decided not to include the player on the preseason tour after considering offers for him.
Dennis is reportedly being looked at by Everton as a possible Richarlison replacement after the Brazilian forward was recently traded to Tottenham Hotspur.
Dennis signed a £3 million transfer deal with Watford last summer from Club Brugge of the Belgian Pro League.
He is currently worth about £20 million to Watford.
