Sevilla, who lost the UEFA Super Cup to Real Madrid on Tuesday, said that they had reached "an agreement in principle" to sign the 20-year-old, adding that the deal would be concluded once the player has undergone a medical on Monday.

Barcelona added that the move was "designed to maximise the participation and optimise the sporting development of the player."

Deulofeu spent last season on loan in England with Everton, whose manager Roberto Martinez had been keen to bring the player back for a second campaign at Goodison Park.

However, the Catalans, who have a new coach in Luis Enrique, had initially turned down any chance of loaning Deulofeu out again, only to change their mind.

Sevilla have already signed former Manchester City midfielder Denis Suarez from Barcelona this summer on a two-year loan.
