Udinese have sold striker Stipe Perica to English sister club Watford.
The 25-year-old Croatian was purchased from Chelsea in 2016 for €4.5m, but never made much of an impact in Friuli.
He was sent out on loan to Frosinone, Kasimpasa and Mouscron.
After 71 games for Udinese, scoring 11 goals in all competition, Perica was sold to Watford on Monday.
