On other hand, I don't think expect Fulham to be able to beat one of the title challengers namely Arsenal previously, apparently they have a secret weapon to make Arteta squad cry all night, even throughout the second half of the season. because in my opinion this defeat will have a very big impact on Arsenal, they will definitely have difficulty overtaking the position of Aston Villa and Man City in the future.
Arsenal are gradually losing their concentration, I understand that there are many factors that influence this, the hope is of course that they can regain their rhythm in the future. But at the moment they are very frustrated, Especially Arteta who has a big responsibility for the team performance.
