Reports in Argentina have claimed that the 27-year-old has already signed a pre-contract agreement with Manchester United, although the defender’s representative, Eugenio López, denied this in an interview with Cadena SER Valencia on Monday.
Otamendi’s agent also indicated that United will need to meet the Argentine’s €50 million (£35.4m) release clause in order to secure a deal.
"Nicolas is comfortable with Valencia and the fans but will have an option to improve his career,” said López.
“Jorge Mendes already knows that Nico wants to leave Valencia. Nico will do everything possible to get it, he will do everything possible to leave.
“If there's an offer from a club we consider a top club, and it benefits his family, Nico wants to go.
"There are many discussions with several clubs who want to sign Otamendi.”
