Thanks for all the replies. I am sharing the screenshots for my tactic and squad. My AMR-AML-ST players are performing really well. I guess I am lucky since those are the important positions.
Both MC's, DR are performing good. DMC is ok. GK-DC's are bad, and my DL is old.
I got a 18 years old DL. Got 9/12 talent with 6 fast counter training. I suppose he is worth of developing.
I also get a GK 18 years old. He recieved 8/12 with 6 fast counter training. I am not very sure whether to invest him or not with green packs. I'll try to get a better fast trainer GK. If I can't get better one, I 'll invest him. If I can't, the one I found couldn't be worse than my starting GK.
I would try to find a DC as well. If I can, it'll be perfect for the next season. If not, I'll get one on next season.
