Everton boss Roberto Martinez admits Barcelona have a buy-back option for Gerard Deulofeu.

The 21-year-old has made five assists in his last seven outings for Everton and netted his first Premier League goal since arriving at Goodison on a 'permanent' basis against Sunderland.

Martinez said: “They can't do that. There are certain things in the deal. They can't take him back in the winter so they can't take him back in January. It can only be at the end of the season. It is 9million Euros for the first year and 12million Euros in the second year.

“If they take him back they can't sell him for a season, so he has to stay in the first-team squad for a season.

“At the end of that if they decide to sell him we have got first rights of getting him back or we have got a big percentage of that deal. There is nothing we can do if they activate it.

“That was the deal and the only way we could access the player in the terms that we wanted. I'm delighted with the deal."
