Manchester United manager Jose Mourinho has criticised Antonio Valencia and Anthony Martial following the Red Devils' 4-1 defeat to Liverpool in the United States.

Martial was given permission last week to leave the United camp in order to attend the birth of his second child but has remained in Europe instead of linking up again with his club.

Mourinho also suggested that he was unhappy with Valencia's condition upon his return to the squad, with United missing a host of senior players for the tour ahead of their final International Champions Cup meeting with Real Madrid on Tuesday.

"We play Real Madrid and we have no more players than what we have," the Portuguese told MUTV. "Antonio Valencia comes from holiday - I think too much holiday for him. His condition was not good when he was back, then injury and also go back.

"Anthony Martial has the baby and after the baby is born - beautiful baby, full of health, thank God - he should be here and he is not here. So we have Alexis [Sanchez] and [Juan] Mata who play every minute of every match and now we have Real Madrid and after that Bayern Munich and that's our start."

Mourinho has also criticised the United board for their transfer activity this summer and the referees who took charge of the ICC game against the Reds in Michigan.
