I feel Ben never got the chance to prove anything at Olympiacos. Injuries played their part as well, ACL injury during 15/16 left him out for the rest of the season, then the club loaned him to Panionios of Ansarifard and Masoud where he had a full season with 9 goals and 6 assists in 28 apps. In 16/17 he returned to Olympiacos. Besnik Hasi used him on the CL qualifiers where he scored twice vs Partizan but after that he had another njuiry and was sidelined. I feel he has quality in general and he's a capable goalscorer, but he needs a regular spot in the team in order to perform.
About the set, there are a couple of things i wanted to look into from my impressions of him from Panionios but we never really got to see him.
I could see his DA and Agi a tad lower, i know his DA was recently increased and i don't necessarily disagree with it but i remember i didn't see his close control quite at yellows. This is probably just be a cosmetic thing, i have him at DA 79, Agi 85 in my game for example. Just something i wanted to check out.
The other thing is his SA/ST. I see him more balanced there . His placement is pretty good ,not exceptional, maybe 76-77. His ST isn't so close to 80s from what i've seen and he has some trouble with 1-touch shots. He's decent at shooting from angles but again i'd rate him at very low greens. His shooting is more about placement in general from what i remember, SP might be worth a look also....eeh just try to check out his shooting
