1st team: Agger, Skrtel, Johnson, Enrique
Backup: Kelly, Coates, Carragher, Coady, Flannagan, Wisdom, Robinson
Fair enough, we haven't got a 'superstar' defense, but I'd say we have adequate cover. With a MF/ FW there's going to be a lot more rotation. Ideally you'd keep the back 4 the same indefinitely, but you're always gonna get injurues/ suspensions- that's where the cover comes in. If we went out and bought Godin (for example), he'd be itching to play regularly and if Agger & Skrtel are in form, he wouldn't get games.
Just my two cents.
