Nicolás Otamendi's future has been in the air for several months. Manchester City seem willing to transfer a CB that, however, is taking it easy, as he has two years left on his contract.
Many teams have shown an interest in the Argentine, such as River Plate and Real Betis at the head, but now it seems that the door is opening to a possible return to an ex-team.
As 'O Jogo' say, Porto are reportedly very attentive to the situation of the City player and are reportedly seriously weighing up bidding hard for him in the summer market.
The information even states that the club's board have already reportedly held contact with Nicolás Otamendi himself to know his availability and if he would be willing to return to the club.
It's worth remembering that the Argentina internationalist played at the Do Dragao between 2011 and 2014. From there he moved to Valencia and then to Manchester City who were then managed by Manuel Pellegrini.
