Some opinions.

I can't tell which of your 5* players are better than the others, but your formation looks good. You'll be quite exposed against AML, AMR and a central ST, though. With your 6* and 7* players, you should be able to do well, but you'll want your future squads to be more flexible, like mine. My DL was a mistake lol, and the ML is pretty limited too. STs and MCs are usually single position, but it's good if you can get them with another position.
