Manchester United were put on red alert after James Rodriguez refused to travel with Real Madrid squad for Sunday’s fixture against Athletic Bilbao.

The attacking midfielder has only played just 14 games across all competitions for Zinedine Zidane's side this season and he is expected to move away from the club this summer.

The Red Devils are closely monitoring Rodriguez situation and are expected to make a move at the end of the campaign this year.

And he was missing for Sunday's 1-0 win over Athletic Bilbao at the San Mames Stadium.

Zidane revealed during his post-match press conference that it was Rodriguez's choice to not travel with the squad.

Speaking to the press, the Los Blancos boss said: "He wanted to be left out because of his own reasons."

Before he added: "The reasons are between us and I'm not going to tell you anymore."

Rodriguez has dismissed rumours that he has fallen out with Zidane.

Speaking to Colombian TV, he said: "There was never any problem [with Zidane]. Each coach has his tastes.

"We have a normal, working relationship.It does not seem fair to me that a person is disrespected for not picking a player."
