I think clubs have used the first few games to learn how Arsenal play. Sunderland was a very good game that showed Premier League clubs have figured out how Arsenal have been getting away with everything.
Starting with Ipswich Town, Arsenal will find it hard to score goals. Saka is ineffective, Havertz has no idea what to do, and Tzolis is a flop. So, it will just take defenders standing firm against their midfield and providing enough cover.
