Benefitting from more astonishingly slack defending, Robert Snodgrass should have put West Ham ahead when he ran clear on goal, but the midfielder let Arsenal off the hook with a tame effort.
"I think they all know we are making too many changes and in the first three games, we haven't had the results that we wanted, but in every game we are improving".
