you saw what city did to Arsenal in Emirates, with Bernado as a left back?? Imagine Sancho is a leftback in Emirates, marking Saka
Can you think they are in the same level.
Have you seen what they have done to Bayern?
Only Klopp was near City level few years back, that's why even games between them we fairly even and hotly contested.
Now is, Arsenal have perfected the art of winning 99% of home games, beat all bottom 10 teams away then fighting tooth and nail in the top 10 away games.
City will beat Arsenal in Emirates. That will be home and away.
United beat Arsenal away. Arsenal at home needed a last minute winner.
Liverpool blew Arsenal away in Anfield. Arsenal in Emirates had a dubious penalty+offside goal against Liverpool to win.
Arsenal in Spurs, their keeper kept them in the game second half like in Anfield.
No single game this season have City been blown away. They are still in 3 different competitions remember. City already has beaten Arsenal twice, 3rd game is coming in Etihad.
Your main challenger can not beat you home and away( it will happen) and you still proclaim you're on the same level.
Arsenal are extremely consistent, that matters alot but they are a level below City.
City have a 45 goal scorer, KDB+Rodri in midfield, and Pep to boot. Competing with such a opponent requires utmost consistency which might not be enough at the end of the season sometimes. Sadly.
