The attacker is now on loan to Ligue 1 side Le Mans and reckons that he might have taken the wrong decision.
"10 big foreign clubs wanted me but I opted for Liverpool," he told L'Equipe. "I signed a five-year contract with an option for a sixth and I am still under contract with them.
"The only thing I regret is speaking to Benitez when he arrived to tell him I wanted to be loaned.
"I thought he would bring plenty of Spanish players so I would never play again.
"That's the biggest mistake I made. I knew afterwards he relied on me. I think I should have pushed."
