Arsenal's streak of consecutive seasons in the top flight began in the 1919-1920 season, following their promotion from the Second Division. From that point onward, Arsenal has remained in the top flight, participating in the highest tier of English football season after season.
This extraordinary feat demonstrates the club's consistency and competitiveness over the years. Arsenal's ability to consistently maintain a strong position in the top flight has allowed them to compete with other elite teams in English football and establish themselves as one of the country's most successful clubs.
During their long-standing top-flight tenure, Arsenal has enjoyed considerable success. They have won numerous league titles, FA Cups, and other domestic honors. The club has also experienced notable periods of dominance, including the "Invincibles" season in 2003-2004 when they went unbeaten in the entire league campaign.
It is important to note that records can change as new seasons unfold and clubs' performances fluctuate. Therefore, it is crucial to stay updated with the latest developments to ensure the accuracy of such records.
