The start of FM23 wasn't fun for me, I lost alot of matches, especially to Man City and Spurs.
Until I had to try alot of tactics and formation, then this one worked.
With this tactics i won couple of matches, had little draws and lost less afterwards.
While with Arsenal, Brazil offered me an international job though they were ranked first Internationally. I won Copa America and resigned. I joined Ukraine with the hopes of qualifying for the World Cup.
Then resigned from Arsenal with this record, I won the EPL, UCL, Carabao Cup, FA Cup the following year using this tactics.
You need a strong attacker upfront, I used Toney or Gapko. If you can get Dias from Man City and R. James from Chelsea please do. Let James take corner kick on both sides, you'll be amazed at how Dias will score from corner.
