Nicolas Otamendi has threatened not report to Valencia training as he agitates for a move to Manchester United this summer.

United have identified Argentine defender Otamendi as a potential target as Louis van Gaal looks to bolster his squad's defensive stocks.

The Red Devils have prioritised the signing of Real Madrid defender Serigo Ramos, but it is understood that Otamendi is also on their radar as a potential back-up plan.

The Daily Mail is reporting that the centre-back has reportedly told Los Che that he wants his future resolved before the club returns to training on July 27.

Otamendi is keen on a move to Old Trafford and is determined to push through the transfer which could cost the Red Devils £35.65million which is the player's buy-out clause in his Valencia contract.
