It depends on what sort of save you want to do mate. I know you mentioned starting with a big team and that's probably the best way to go about it, but ultimately it comes down to what you think will interest you the most. Clubs like Spurs, Dortmund, Atletico or Napoli to name a few might be a good start. They're bigger sides in their league which will help the learning experience as you should be able to find some relative success, but not too easy to where you can just sign all the best players and plug and play your tactics. Basically, it all comes down to what you think you'll enjoy, if you're the kind of person who wants to build amazing squads and win lots of trophies, a club like Man City or Man Utd might be ideal for you, but if not, you could try some of those I mentioned above.
