Despite being naturally left-footed and thus having an advantage on the left sided CB spot, the potential for Cornelius to be sitting on the bench during many MLS matches this season may be quite high considering the investment the club has put into the other international CBs they have brought in (Godoy, Khmiri, and Veselinovic). As I said in the Jakovic thread, CB is such a fluid situation for our NT right now but I sense that the coaching staff have their favourites and will continue to use them ahead of others even if those particular players are seeing little playing time at club level. However, Cornelius didn't feature in the Iceland friendly, with Miller chosen ahead of him (injury?), and he's going to have to pick up his game pretty quickly with the Caps if he's going to be a first choice CB starter there going forward.
Like everyone, Waterman has to keep proving himself at club level and keep showing improvement, avoid major mistakes but not dwelling on them if those gaffes do happen (that's a problem with Henry, imo: when he makes one mistake, it usually mushrooms into more in a short period of time).
I look forward to watching his future matches.
