Every Current Premier League Club's Biggest Transfer Bust
3. Watford - Andre Gray
At the time of writing, Watford is currently engaged in a battle for survival at the foot of the Premier League table where goalscorers are worth their weight in gold.
With that being said, it's still hard to justify Andre Gray's signing for a club-record fee reported to be in the region of £20 million back in 2017.
Gray had established himself as one of the top goalscoring talents outside of the top flight prior to his move to Vicarage Road but has been unable to recapture his once unstoppable form, managing just 14 goals in 80 Premier League appearances since his move to the Hornets.
