Czech goalscorer will leave if Hornets fail to go up.
On loan Watford striker Matej Vydra has put a number of Premier League clubs on high alert after admitting that he will move on should they fail to secure promotion this month, according to the London Evening Standard.
The 21-year-old who is currently on loan with Watford from Italian side Udinese has made a name for himself this season by notching 24 goals in 50 games and has attracted the attentions of a number of Premier League sides.
QPR, Spurs, Fulham and Aston Villa have all been credited with an interest at various points during the campaign will now be put on high alert as the Czech Republic international has announced that he will look to move on should they fail to overcome Crystal Palace in the Championship play off final later this month.
He has made it clear that he would strongly consider another season at Vicarage Road if they make it to the top flight, but failure will cast his future into doubt as he is behind Antonio Di Natale and Colombian forward Luis Muriel in the packing order at the Northern Italian packing order and may struggle to re-establish himself should he return.
Vydra is valued at just £5 million, but it is thought that any club wanting to sign him will have to pay significantly more than that to secure his services as his contract with Udinese runs until 2016.
