Watford have signed former Everton winger Gerard Deulofeu from Barcelona, the Spanish champions have confirmed.

The 24-year-old spent the second half of last season on loan at Vicarage Road, scoring once in seven Premier League appearances for the Hornets.

Deulofeu will now return to Hertfordshire on a full-time basis after Barcelona announced a deal worth an initial €13 million had been agreed.

Announcing the deal on their website, Barcelona said in a statement: “FC Barcelona and Watford FC have reached an agreement for the transfer of Gerard Deulofeu to the English club.

“They have agreed on a fee of €13 million, plus €4 million in variables. FC Barcelona will also receive a percentage of any future transfer operations to other clubs.”
