The English premier league is survival for the fittest. Consistency is the only active factor that matters in football, especially in elevated competitions. Arsenal lacks the consistency to keep winning games, ceding points to mediocre clubs, and bargaining with equal strength in the last days of the Premier League season. Pep Guardiola knows his former colleague's weaknesses and made advantage of them, streak winning games and putting the gunners' confidence fully on the point of defeats, meeting them numerous times and winning them in all phases.
Yeah consistency is the key behind any club's success but with Arsenal, they started very well and were consistent for almost most of the games until the injuries to the crucial players hit us and we started to wobble a bit and dropped lot of crucial points we needed near the end of the season. Still we did our best and managed to finish 2nd which isn't bad considering how we have struggled to get into top 4 over the years. Arteta is making team strong bit by bit so I am confident that if things goes like this then we will be able to win PL soon in coming years.
