Barcelona have re-signed winger Gerard Deulofeu from Everton after exercising a buy-back clause believed to be worth £10.6m.

Deulofeu originally went on loan to Everton in 2013-14 then signed in a £4.3m permanent deal in 2015.

The 23-year-old made 13 appearances for Everton last season before joining AC Milan on loan in January.

The Spaniard, who came through the youth academy at the Nou Camp, has signed a two-year deal.
