firstly i wouldnt panic, im level 3 at the moment and there are only 2 other decent teams in my league, so i highly expect you'll find yourself in a league you fancy you can win.

Secondly, yeah not great to have no tokens or cash, but don't forget your prize money for finishing in the top 7 of your league this season, which i think from memory is about 1.5M+ depending on your finish. Also don't forget, if you're top 4 this season, you'll be entered into the Champions League next season and guaranteed 6 group games which bring you 240k per game, so thats another 1.5M you can count on reasonably early in the season. Then there's the sponsor contract, so thats another 600k you can have on day 1 or take the 2-weekly contract to get 330k now and 330k at half way in the season.

I'd avoid the first week in terms of buying players, but then start to look round, you'll have a few more by then and can hopefully pick off a couple of players for 1-2 tokens. Don't panic about your squad not being fully 6* though, it really doesnt need to be great to win at level 3, the level of competition is not exactly strong!

Best of luck
