My main team on level 24 has 3x 5* ST and one of them has attacking skill on 7* level. However, none of them scores enough.
Meanwhile my 2nd team Dnipro on level 18 has AML and AMR which are in great form, have excellent scoring and assisting stats, so that's why one of ST's in this club follows them with good appearences.
And my other team, Celtic on level 13, has 4, 5 and 6 stars ST's, and my 4* ST has better statistics than scout, but the best one is 5* ST who scored over 10 goals this season.
All in all, I have had more effective ST's (in both quantity and quallity).
