Since when, the best of clubs, ever relied on a single striker and their indolency to win was blamed on a striker alone? Especially, the one that never relied on a classic #9 in their play scheme. Liverpool in 1980s was winning and formidable even though Ian Rush had scoreless stretches too. Arsenal too, was just as winning without Brekamp finding net,... I could go on and on...
The thing is, everyone of them can shoot and score, why can't they?
Drop Lewa and see, it ain't getting any better...I tell you what, it'll get worse and you'll miss him all too soon.
