Everton have confirmed the signing of Barcelona winger Gerard Deulofeu.
The 21-year-old has signed a three-year-contract - with the option of a further year - in a deal worth £4.2million.
Deulofeu impressed on loan at Goodison Park in the 2013-14 campaign but returned to his parent club and was subsequently loaned out again to Sevilla.
However, Toffees boss Roberto Martinez, who had a good relationship with Deulofeu, has kept tabs on the youngster and moved quickly to make him his first signing of the summer.
Deulofeu - a product of Barca's famed La Masia academy - made 29 appearances during his first stint with Everton, scoring on his debut in the Capital One Cup against Stevenage and going on to add three Premier League goals, including a memorable equaliser against Arsenal at the Emirates Stadium in December 2013.
Although he played a similar number of matches at Sevilla, scoring three times, his form tailed off towards the end of the season and he found himself on the bench for most of the run-in. He did not even make the squad for the club's Europa League final victory.
He accepted he had a more testing year than he had expected, writing on Instagram last month: "A tough and difficult year for me but perhaps it's also the year in which I've learned the most."
Martinez will hope to get more out of the player than managed by Sevilla coach Unai Emery, whose assessment was at best mixed. "He has incredible qualities but lacks others. Put him out there, one on one and ... pfff," he said.
"But make him play football with team-mates, on a big pitch, and it's hard. He doesn't have the maturity or capacity for sacrifice yet."
