But why risk this? Trying to build his confidence back up, when we could go out and buy a ready made, confident keeper that can play a part for us in our new team. Like all sports, success begins in the mind. If Guzan has got issues with his confidence, it's not worth the risk imo.
Also, the (new) defence needs to feel confident in his ability. At corners, free kicks etc.. Can you really be sure Guzan's going to dominate his area.
