Arsenal showing championship form.

One won't find a more in-form team than Arsenal right now. In the last few matches, they have been absolutely dominant both in terms of results and gameplay. They are very much in contention for the English championship, and now a Champions League match against Porto awaits, where they are also chasing success. 

Arsenal's last five matches: 
◉ 0-5: Burnley vs. Arsenal
◉ 0-6: West Ham vs. Arsenal 
◉ 3-1: Arsenal vs. Liverpool 
◉ 1-2: Nottingham vs. Arsenal 
◉ 5-0: Arsenal vs. Crystal Palace

An impressive total of 21 goals have been scored in these matches, resulting in an average of 4.2 goals per game. The offense is currently flourishing, with Saka particularly showcasing great form with 6 goals in the last 5 matches. Defensively, they are also absolutely solid, as Saliba and Gabriel have proven to be a well-functioning defensive duo, working in harmony with the rest of the team. Right now, they are collectively a cohesive unit with tremendous confidence.

In the Champions League, Arsenal comfortably advanced as the group winner, and now they face FC Porto. On paper, Arsenal is the favorite, and with the current quality they are displaying, it's challenging to see how Porto could halt this well-oiled machine. Arsenal is now entering a phase of two tournaments per week, so it will be crucial to avoid injuries and ensure players don't run out of steam towards the end of the season if they want to claim one of the major trophies this year. Arteta has a tendency not to make many changes in the squad, and it will be interesting to see how they respond to the demand of playing important midweek matches as well.

It seems that Arsenal has hit top form, and if they can maintain it for the rest of the season, they should be considered one of the major title contenders. They have learned from last season's championship race with Manchester City, and the work Arteta has done with this team is impressive.
