Arsenal have been continuing to impress me on the weeks we have left behind. They have just magically changed everything about them. I have no doubt that everyone here remembers how terrible start they made to this season. They were like losing every single match of theirs by big goal margins. Arteta was on the brink of getting sacked. But suddenly, something started changing about them. And they have arisen with the same manager. And thanks to their current winning streak of four matches, they have got the 4th position in the standings. Tottenham are right behind them by a 6-point gap maybe but they have three missing matches now. But this still doesn't change the fact that Arsenal are having a very satisfying season for their supporters also.
I also point this, but I'm not sure they will continue to the next week. so far in the 5 last games, Arsenal has not fought versus a strong team yet, and begin next week they will meet a strong team like Manchester City in the premier league and Liverpool in the FA cup. as we can see, they performed well be testing, if they can hold the win that possible can get at least 1 title.
I see low chances of winning the championship. Manchester City and Liverpool they will face are the strongest teams to be champions. Arsenal, on the other hand, is in the recovery phase. They got wins, yes, but as you said, they haven't tested themselves with a strong team yet. If they can beat Manchester City and Liverpool in both lanes, I will expect surprising results from Arsenal. It is also very good that they scored 10 goals against Sunderland and Norwich. They are showing that they will gradually get better.
