i think all depend on formations, yours and oponent, though, i play with 1 striker and 3 atacking mudfielders and my st scores apo 20 goals in season in all competetions, most goals for me comes from wingers, and i noticed that 1 on 1 does not help much, at least to me, so i rather take st-amc with dribling skill if i find it on market.
Seems some skils are broken, since i switch my pk taker who have pk skill with free kick skiled player or shadow striker my team miss way more pk than before
