Everton manager Roberto Martinez has insisted that Gerard Deulofeu has the potential to become a world-class player.

Despite missing part of the season due to injury, Deulofeu has impressed during a loan spell from Barcelona, and Martinez has no doubt about the 20-year-old's potential.

"Everyone that has seen him knows that he has such natural talent and has the ability to undo teams," the Spaniard told reporters ahead of Saturday's game against Southampton.

"I am convinced that he will become a world-class player."

Reports earlier this week suggested that Deulofeu will spend a second spell at Goodison Park next season.
