Watford boss Javi Gracia has no doubts about the potential of Nathaniel Chalobah.
Troy Deeney has claimed Chalobah's value will rise to £50m in 18 months' time.
Asked what he made of captain Deeney's comments, Gracia replied: "I agree. But not only Chalobah, all of the players we have in this moment, for me, they have high value.
"You never know what happens in the future because many times, it depends on many circumstances. For me, all the players are very good players. I'm sure all of them have high value."
