Porto are ready to sell Argentine international Nicolas Otamendi, according to Goal.com.
The defender's long term future remains uncertain in Portugal and with the Premier League's elite clubs interested in the star, he could now move to England in the near future.
It remains to be seen as to whether any of the clubs will make a move for the Argentine ace in this window.
Manchester United boss David Moyes has already revealed that he will make a number of changes to his squad in the summer and the Red Devils boss may have to battle the likes of Chelsea and City if he's going to secure the services of Otamendi.
Manchester United recently secured a club record signing of Chelsea playmaker Juan Mata for £37.1m, but could still add to their squad before the end of the month.
