Großkreutz is a lot better attacking RB than he is a winger...he's strong as an ox,he runs like crazy and he has the stamina of a Kenyan.
BVB is so much better than last year...they lost Goetze and Lukas is injured but they added Miki+Aubameyang+Hoffman+Großkreutz as a RB+Durm+Sokratis+mentally recovered Sahin.
Last year they had NO substitutions up front...once Goetze went down,the only available player was Schieber and he's atrocious.Now they have 5-6 players that can score at any time.Losing Goetze not only brought Miki+Aubameyang but that meant Lewa would stay as well,otherwise he was certain to leave.And he's 10 times more important for BVB than Goetze ever was.
Replacing him will be almost impossible.He has such an amazing chemistry with Reus,it makes no sense that he's so desperate to leave but whatever.
