Reports in Marca suggest that Barcelona could make moves for Porto pair Nicolas Otamendi and Eliaquim Mangala.
Stories emerged earlier this week that the Blaugrana had decided not to sign a centre-back this summer after having moves rejected for Daniel Agger and David Luiz.
But the Madrid-based newspaper has claimed that Tata Martino’s men have had second thoughts, and could offer for one of the Dragoes defenders.
Otamendi has become ever-present for the Portuguese side since his arrival from Velez Sarsfield in 2010.
22-year-old Mangala meanwhile, has made his debut for the France national team this year.
