Everton manager Roberto Martinez has revealed La Liga champions Barcelona can activate a buy-back clause in Gerard Deulofeu's contract.
"There is nothing we can do if they activate the clause," said the Everton boss. "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.
"There are certain things in the deal. It is €9m for the first year and €12m in the second year.
"They can't take him back in the winter so they can't take him back in January. My worry would be to lose him in January. That would be a big problem."
