Porto are reportedly keen to re-sign Eliaquim Mangala from Manchester City, just two years after the defender left the Portuguese outfit to move to the Etihad Stadium.
Incoming City manager Pep Guardiola is expected to oversee a handful of big-money transfers this summer, and one player that could be out the door is Mangala.
According to O Jogo, Porto are keen to welcome back the 25-year-old, who was sold for £31.8m.
Mangala, who spent three years playing for Dragoes, struggled to make an impact at City having been part of a shaky defence during Vincent Kompany's injury absence.
