I started in the Israeli National League. My reputation is still lower than 5,000. All the fairly good players I can bring are over 34 years old.

My team is not the worst team in the world, but they are certainly not at the level of Barcelona, or current Super Cup + UEFA Champions League holders Atletico Madrid which I've beaten 2-0.
With the players at my disposal an AI manager would get my team to an ending position of say 8/12. There are much better teams in the league and certainly you can't argue that the European giants are far better than me.
I'd be happy to show you some player screenshots so you can see the level my team is at. Like I said, it's not the worst team in the world but its an Israeli Premier League team.
Before I started building this tactic I wasn't even challenging for the title. I was finishing 8th-5th every year
