9) Robert Lewandowski – Borussia Dortmund
The rangy Polish striker will not be at Dortmund beyond the end of this season, as he is choosing to let his contract run out. Whether the Bundesliga club can maintain their level without him is questionable, as he’s been simply outstanding in 2013. He fired Dortmund to a Champions League final, notably scoring four goals in one match against Real Madrid in the semis, before finishing last season with a fantastic 36 goals. This term, despite the uncertainty surrounding his future, the 25-year-old has still found the net 16 times already.
