Few solutions come to my mind.
(1) Push Gerrard back to CM, and move Benayoun behind Torres.
(2) Directly Replace Alonso with Lucas. The lad's got talent but lacks experience. I am also not sure of his ability to play as deep vying playmaker. He is more of a box-to-box kind of midfielder.
(3) Change formation to a classic Ajax 4-3-3, with Gerrard and Lucas running the strings in the midfield and Babel, Torres, and Kuyt as the forward line.
(4) Push Gerrard to CM and sign a quality striker to partner Fernando Torres in a 4-4-2 formation.
(5) Sign Sneijer and van der vaart.
Code:
Casillas
Ramos Pepe Albiol Arbeloa
Diarra Alonso
Ronaldo Kaka Robben
Benzema
They look good.
