Watford face a battle to keep hold of Stefano Okaka.

The Italy international has impressed for Hornets under manager Walter Mazzarri - so much so that he is being lined up for a Serie A return.

Sister club Udinese are targeting Okaka for next season.

Zebrette coach Gigi del Neri is a fan of Okaka and sees him as a replacement for Duvan Zapata.

However, Watford management are sure to protest against any attempt to prise Okaka away from Vicarage Road this summer.
