So I'm coming back to this old thread here to give my final review on the versatile attacker SA. The player I gave it to back then was now dropped to the bench after playing close to 500 matches for my club and scoring 373 goals, which translates to about 0.75 goals per game. Regarding assists he was not flashy or anything as well.
Mainly I used him as an AMC, but sometimes also as a 2nd striker, for most of his career alongside Klose. Klose has a goal per game ratio of 0.81 with just the normal SA 1on1 striker and another useless second SA.
(Please note that my best scorers are my AML and AMR, so these 2 were 3rd and 4th scorer in my team respectively)
I didn't notice any special things he does better than other players. Of course it is hard to tell for me as I don't use the 3D animations in the game and play text mode. Overall he was decent, but nothing more.
To conclude I can not really recommend the SA, however due to the lack of useful SAs in the striker department, I could see myself using it again in combination with 1on1 striker on another player playing mainly as ST.
