i kind of think since dani alves coming up so much it might be better to have a left back that stays put more... like abidal.. i do not think we should stress to much over the left back spot.. abidal is capable
And if for one reason or another Alves or Abidal can't play?
We would lose our attacking flair from the full back position in Dani's case or a left back as Abidal is our only player in this position.
As a few have noted before, if we get an attacking left back like Zhirkov that means we can either use:
Alves & Abidal (attacking right, defenside left)
Puyol & Abidal (defensive right, defensive left)
Puyol & New Left Back (defensive right, attacking left)
Alves & New Left Back (attacking right, attacking left)
It provides us alot more cover and hands us more options to play with if/when we need to adapt.
Il be honest i've not seen much of him other than his performances in Euro 2008 but he impressed there and everything else i've heard from the other users has been positive. I'd love to see him join the squad and he'd likey get plenty of playing time.
