You should rethink that. Theyre top notch players. Aquilani becomes one of the best DMs in the world in short order and Benayoung is an extremely valuable piece to have. He's a world class player and he's versatile and can play all over, too.
I never understand these people who take over Liverpool and immediately sell guys like Aquilani, Benayoun and Babel. Sell Babel if youre hard up for money, but Aquilani and Benayoun are two of the strongest pieces on Liverpool. There are place to upgrade Liverpool, but that's not the place to do it IMHO.
