Robbie Keane skipped Liverpool's 1-1 draw with FA Cup opponents Everton yesterday.
The Daily Mail says Keane's Liverpool future has been thrown into doubt again after he responded to being axed by staying away from their 1-1 FA Cup fourth-round draw with Everton.
The £20million summer signing went absent after not even making the substitutes' bench.
He has grown increasingly frustrated at failing to gain a regular place in Rafa Benitez's starting line-up.
Benitez added insult to injury by suggesting French youngster David Ngog had done more to merit a place on the bench.
"I have not seen Robbie, but I know all players want to be involved with the squad and may not be happy at being left out," he said. "I decided not to select him, that was all. He is not injured, but Ngog scored two goals for the reserves the other day, so he was a good option."
