Former Manchester United striker Federico Macheda is trialling with Watford.
The Watford Observer reports Macheda was a surprise inclusion in Watford Under-23s' team in their 4-2 defeat at Hull City on Monday night.
The 25-year-old Italian forward, who left Cardiff City this summer, scored a goal for Harry Kewell's side as a trialist in their game at the KCOM Stadium.
Former Barcelona right-back Godswill Ekpolo also played as a trialist for the Hornets in their latest Professional Development League match.
