I personally think Lewandowski will be released this season to the Saudi Pro League the reason Lewandowski is no longer reliable and his contribution to the team has been low this season so it was the right choice to let him move, especially since the Saudi Pro club was willing to pay a high price to bring him in. Previously I checked the top scorer list and didn't see Lewandowski name so I assume he is no longer able to compete, Barcelona should realize that there is nothing more they can expect from this 35 year old man.
Ok I won't say that Lewandowski won't go to the Saudi Professional League, but from what I understood last time when he was approached by a club from Saudi Arabia is that he doesn't want to go to that country and play there. Now money can change his opinion, but I am sure the offer he received last time must have been huge if we take into account that Benzema also got such an amazing offer. He has two little girls as children and maybe he isn't the kind of guy to go there? That's an interesting question though.
