There are many alternatives to build a team. You may choose yourself a style you like.

The simplest approach is keeping a full squad with players for two 4-4-2 formations. Then even if you face quite severe injury problem, your team can still use formations which are not too weird.

I tend to keep full squad. I believe this may be the actual solution for many managers who complained about injuries. In the past, I heard that team will suffer financial crisis in high levels that they cannot keep too many high wage players. But I still don't feel the problem after Nordeus increased the competition prize and my teams' cash balance are kept increasing.

If you are afraid of bidding wars, you may buy less attractive players (those with qualities end with 0,1,5 or 6). If you are lucky, you can get unexpected fast trainers from these players.

For this season, you can also temporarily use the old free agents. These players are 3 star but many old players are really consistent and reliable.
