your team is ok...BUT

I would start to pick up players that have more than one position. I.E. AML/ML, DMR/DR, DC/DMC.
You can have less players playing more positions and allow yourself more players on your roster that are multi-positional in case of injuries.

When I moved to 2nd level (just last season), it was a shock. I won the treble but I almost sold and bought new players for every position as I was not prepared for the lack of skills for that level. You will sell your worst players and buy ones better than your current best. I think I have 3 players who are still in my team from LVL 1, but they are fast trainers and I am sure they will be replaced next season or 2.

My advice: spend $10 and get 80 tokens for upgrading your players. Its only $10 but you will be preparing for LVL 3 while you play LVL 2.

Good luck in LVL 2
