I'm not sure you watched the game pal. They didn't overrun us at any point, they got a major slice of fortune with a massive fuck up in defence gifting them a goal, second was an overhit cross which they got a huge slice of luck with combined with some level of goalkeeping error and the last goal was a great through ball that our defence didn't bother to track the runners for and forced our keeper into kamikaze action.
They took confidence from our own defensive errors, they didn't suddenly start dominating once Nunes dropped in as the 6, you've created a link to 2 things that had no credible link. You may aswell blame James Mcatee's introduction to the game as the cause of our collapse, there's about the same level of credibility to that claim as there is laying any at Nunes.
