He might be at the moment but thats not solely because of his greatness. In world football theres a lack of really good strikers currently. Suarez was a lot better. Also Benzemas technique and link-up play is far superior.
I'm part Polish and watched Lewandowski a lot.
Lewandowski's technique as a 9 is second to none.
Zlatan's is more flashy but Lewandowski's is more effective. You're really underrating Lewandowski here.
You're also quite shortsighted to see Lewandowski and think his technique is poor simply because he is tall and strong. You clearly haven't watched him, at all.
