The 20-year old Czech Republic striker, on a season-long loan from Udinese, has scored 20 goals for the Hornets so far this campaign but is unsure at this stage what his future holds as Watford chase Premier League promotion.
"We'll see if we win promotion or stay in the Championship," Vydra told CTK. "I like it at Watford and would like to continue to play there.
"After all, I've built something there already.
"I don't know if I'm ready for it (the Premier League), but who would not like to try this competition at my age. Even younger players are there, but we'll see."
