"If the situation remains the same over the next few months, and I'm not getting more time in the middle, I will not want to continue as a Liverpool player," Benayoun said on Israeli television.
"The fact that I have spent so much time on the bench, while there has been a winning formula on the pitch, tells you everything.
I hope it changes for me, because I want to stay and prove myself, but it won't be easy.
"Even if it's Liverpool, if I don't get to play in the next few months I will not want to be here. I've enjoyed my time in England but maybe it is time to learn a new language... maybe Italian, French or Russian."
Benayoun was signed for £4m from West Ham United and got considerably more action last year, but as Benitez continues to improve his squad, the Israeli is finding it difficult to motivate himself.
"When I came here it wasn't so I could tell everyone, 'Hey I play for Liverpool'. My purpose was to prove myself, and in the first year I think I did. I understand that I am at one of the biggest clubs in the world and that this year there are better players. There are many good players like Ryan Babel and Jermaine Pennant who sometimes aren't even in the squad, but it's not much fun sitting on the bench all the time."
