Sanchez, left side of Osasuna, on loan from Atlético de Madrid, has had to withdraw from training due to discomfort in the back of the left thigh that has not allowed him to finish the session with the group.
The young footballer was a starter against Real Madrid and this morning he was unable to finish the session with a red squad that has returned to work after the two days of rest that Jagoba Arrasate gave them.
Arrasate has directed an activation training, technique, possessions and a soccer game in which Rubén Martínez and the Argentine Jonathan Calleri have not participated, the only players who continue to recover from their respective injuries.
Osasuna faces a special week that will end on Saturday with the match against Athletic Club starting at 9:00 p.m.
The need for the Navarrese to sign the permanence mathematically as soon as possible implies that the Arrasate pupils must thoroughly prepare the clash belonging to the thirty-fifth day.
