I still remember the meme that depicts Arsenal as an elephant sitting on a tree branch. The way Arsenal failed to win a trophy is still the same last season, where they still lost consistency in the final third of the season, we realize, that Arteta is currently missing several key players due to injury. The next match against Manchester United will clearly be very difficult, even though on paper they are more favored. Nottingham Forest, Manchester City and Chelsea will continue to put pressure until the end of the season, Arteta must now focus more on maintaining his team position in second place, no longer thinking about how to compete for trophies with Liverpool.
Arsenal have destroyed PSV in Philips Stadion, I don't think it's gonna be a hard match against Manchester United. Manchester United not even able to beat Real Sociedad. Arsenal lost several important players, but don't forget Manchester United almost lost half of their players.
Liverpool to not become a champion in this season is like 1% because they have many match against weak teams: Southampton, Everton, Fulham, Leicester City, Tottenham and Crystal Palace.
