According to ESPN's James Olley, Chelsea's coach Thomas Tuchel wants Robert Lewandowski to replace Romelu Lukaku at the club this summer.
However, there are certain obstacles that make the transfer difficult.
First of all, Lewandowski is prioritizing a move to Barcelona at the moment. And even if the Catalans can't sign him, clubs like Manchester United and Paris Saint-Germain will also go after him.
Besides, Chelsea have to offload Lukaku first, which isn't an easy task either.
Meanwhile, Barca saw their first offer for Lewandowski ignored. They are preparing a second bid which could be as high as €550m.
