On closer inspection, it appears the downturn in form may be down to international retirements. As far as I can tell the following players have retired from international football...
Hawkwind, Hawkins, Romeo, Conron, Del Conte, Juggernaut, Shaw, Gotts, Naterr. There may be a few more as well who are injured currently but as far as I can tell there isn't anywhere on the game which tells you whether someone is retired from international football?
James Scott is the new captain and Charley Mason is vice captain. Matthew Hawkins is now the all time top appearance maker with 110, with Del Conte the top goalscorer with 40.
