Zarate looking to make a return
The Argentinean striker has had stints with Birmingham, West Ham and Queens Park Rangers. But the Hornets manager Walter Mazzarri believes he can tame the fiery Fiorentina star and is close to tying up a loan deal reports claim.
The 29 year old ended his spell with West Ham when he joined Fiorentina on a permanent contract for a fee believed to be £1.6m.
He has scored four goals in 18 appearances this season, but just half of those appearances were Premier League starts.
At the time Zarate said “I would like to thank David Sullivan and David Gold for believing in me and for giving me the opportunity of playing at such a special club like West Ham.”
