An unnamed Premier League club has made a bid for Matej Vydra, the striker's agent confirmed to the Watford Observer.
We contacted Vydra's representative Ondrej Chovanec yesterday and last night he confirmed a Premier League side made an offer last week.
Udinese rejected the bid which Sky Sports claim was an £8m offer.
Chovanec said there are a lot of Premier League and Bundesliga clubs interested in Vydra but stressed he would not comment on every bid moving forward.
Initially Chovanec had claimed there was "no news" regarding Vydra and stated a decision over his future had yet to be made.
He reiterated Vydra, who has two years left on his contract at Udinese, wanted to play in a "top league" but stressed they were "looking for the best proposal for the club and the player".
Chovanec added: "Matej spent a wonderful year with Watford; he was very well supported by the club and also by the great fans. He would like to thank all of them.
"He has a two year contract with Udinese Calcio and there is not yet a decision regarding where he will play next season. He does wish to play in a top league."
Vydra won the Championship Player of the Year award during his first year in English football.
The 21-year-old scored 22 goals on loan at Watford last season but that did include a barren run of no goals in 13 games before his double in the play-off semi-final second leg against Leicester City.
In January Chovanec said five Premier League clubs were interested in Vydra and there had been "two or three proposals".
Chelsea, Tottenham Hotspur, Arsenal and Everton are among the clubs linked with the Czech Republic international.
The agent said at the beginning of June that he couldn't imagine Vydra playing in the Championship next season but that was at odds with what Udinese owner Gianpaolo Pozzo had said the previous week.
Pozzo was asked whether he expected the Hornets to retain Vydra and he replied: "Absolutely; we want to make the team stronger to do better. He will stay at Watford." And when asked a similar question, he responded with "of course [he will stay]."
