We need a left back.
In my opinion it horribly un-balances our team. Martina isn't the greatest player in the world, but he's a better right back than a left back. By bringing in just a good left back, right there we improve on 2 positions. Also, we might not have to have our left mid/winger babysitting him anymore which would be nice to see. Might move another player a little bit more forward.
