A left back, left winger, and centre back and we could be a force.
Taye Taiwo (free)
Albrighton? (If he's left sided)
Phil Jones
Although, a fair few of the current lot should leave, and Kelly used more as a centre half.
I'd rather see a slightly more established centre-back, possibly Hazard for the left side?
Would like to see Skrtel (as much as I love the guy), Johnson, Cole and Maxi leave. Still unsure about N'gog.
