FC Porto pair Eliaquim Mangala and Nicolas Otamendi are reportedly interesting Barcelona, having previously been linked with both City and Chelsea.

Back in October, a number of reports claimed Chelsea had agreed a deal to sign FC Porto defender Nicolas Otamendi next summer.

The story stemmed from Spanish newspaper Marca, which claimed that despite interest from Barcelona and AC Milan, the Argentina international would move to Stamford Bridge.

And then everything went quiet, until the same player was linked with Manchester City, along with his club-mate and fellow defender Eliaquim Mangala.

At this point, both are still very much Porto players, with Mangala tipped last week to be offered an improved contract in an attempt to ward off potential suitors.

But now Portuguese newspaper A Bola has picked up on claims from Spain that Barcelona are paying close attention to the defensive duo.

Newspaper Sport claims Barcelona’s sporting director Andoni Zubizarreta rates both players extremely highly, as he continues his pursuit of new defenders for the La Liga champions.
