The reason he has been in the team for the last few years, is mainly because he is reasonably competent. Not s**** but not great. Just good enough so that the manager can address other, more important, areas of the team while "making do" with Riise at left back. Hopefully, we've now addressed the issues in those other positions and we get a really good 1st team left back. As good as Finnan is on the right. I'd keep Riise though, his versatility is useful as a squad player, he's never injured and looks one of the fittest players in the squad. Also - has Aurelio stayed fit last season, I think he'd have played left back in the final. He was starting to do really well.
