Absolutely. This is just common sense. If we're going to seriously challenge then we need to be strong all over the pitch. There are threads suggesting we give Chamakh another season, give Wenger another season, get along with the CBs we already have, and also give a rookie the #1 shirt. These collective weak points add up. Maybe you can carry one weakness in the team, even two if the team as a whole is good enough (which we aren't), but several fundamental weaknesses? We all know what happens when you do that, we've seen it. I'm not referring to Chesney's ability as a weakness, merely his lack of experience. He plays in such a crucial position, he needs to do his time like any keeper who ever made it to the top. Bear in mind, we'll probably be partially carrying two rookies in the engine room as well, Wilshere and Ramsey. Fine players both but again, where's the experience?
