If Bayern receives a perfect offer from Barcelona, Lewandowski will be let go. If Barcelona raise their offer to €60 million, Bayern will sell Robert Lewandowski, reports say. It won't be good to continue Lewandowski's career at Bayern, so it would be better to focus on other things. Apparently, he wasn't in training, then why Bayern would sign someone like that.
Lewandowski is Bayern's best striker to date and has scored many goals for Bayern, then it's actually a big loss for bayern if they let lewandowski off as a free agent next year. €60 million is not money that will be easy for barca to get (looking at their current financial condition), so I believe that barca will try to continue negotiating for bayern to reduce lewandowski's price.
It seems that Barcelona really want Lewandowski to play for them. From the start of the rumors about him, until now Barcelona are still pursuing a deal for this player. The efforts they have made so far are still deadlocked, where Bayern Munich is still holding back the price of their goal-hungry striker.
