Ole Gunnar Solskjaer has revealed why Edinson Cavani missed Wednesday's loss to West Ham United.
The Uruguayan has played just once for United this season.
And Solskjaer says the veteran striker is still working his way back to full fitness.
"(Cavani) has not trained enough to be part of this," said Solskjaer before kick-off.
"He is working hard and he knows his body better than anyone. He will put his hand up when he is ready."
