Don't agree there.
I watched him a lot if 2009/10, and he's definitely got ability.
He's never been the greatest defender, that said, he was very solid at the 2010 World Cup, but at his best he's a very clever, technically skilled fullback. Very quick as well, and can run all day long.
Wenger would help him get his confidence back and get his development back on track. Still don't reckon this will happen though.
