Barcelona are reportedly interested in Atletico Madrid's Saul Niguez.
According to Mundo Deportivo's Xavier Munoz (h/t MailOnline's Jordan Seward), the club have long admired the midfielder and secured a right of first refusal on him as part of the deal they struck when selling David Villa to Atletico in 2013.
Their interest has been reignited by the 23-year-old's showings for the Spain national team, though it's said he has a buyout clause totalling £134 million (€150.5 million).
