I guess the story is clear now to everyone who is still doubting the capability of this Arsenal side because they are so focused and dedicated to achieving the objectives for the season. They have shown so much courage and strength today, they have proven that they can do it and they can be title contenders this season. Kudos to the team they have been impressive and proven everyone wrong. Indeed they are a better team this season.
Let's just hope that Arsenal don't go back to their clownish ways of winning big games but then losing points against outsiders. As bad form as Liverpool may be, 3 goals against them in such a competitive match deserve respect.
By the way, in the next round Liverpool will play at home against City

I don’t even know what to suggest here - whether Liverpool will finally win and help Arsenal consolidate their leadership, or whether Liveprol will lose and fall into the bottom half of the standings.
Judging by level of the Arsenal team in terms of the quality of the squad and their performance this season I don't think they will finish at any position lower than top four even if they return to their clownish way as you call it. I know Arsenal always lose most of their games against top teams and gain points against lower level teams and we see them winning games against Spurs and Liverpool already, I think this is a good sign and good step to better season and big achievements to come
