Aside from regulars Leighton Clarkson and Jake Cain, the majority of Lewtas' FA Youth Cup-winning side from last season have now moved up to U23 level.
And yet, with five wins from their opening seven games, the Reds sit just two points behind Manchester City in the U18 Premier League North table.
Newcastle United visit the Academy on Saturday, in a game you can watch live on LFCTV GO from 1pm BST, and Lewtas is hoping his team can continue where they left off before the international break after hitting Everton for six in the mini-derby.
