It's quite natural considering they need a striker now because some of their strikers can't back up when Benzema isn't playing or not doing well
If only to be used as a cover for Benzema, Lewandowski would not want to wear the Real Madrid uniform, because Lewandowski's standards are not as a bench warmer. Real Madrid and Barcelona have shown interest in signing Lewandowski, if Real Madrid cannot guarantee Lewandowski is in the main squad, he will choose Barcelona as his new club.
It's a shame because Lewandowski himself really wants to strengthen Barcelona before retiring, but Bayern Munich is unlikely to let him go until his contract runs out. If this is true then the team that will get Lewandowski when his contract expires will of course get it for free, I don't understand there are still teams that don't want to make a profit. Instead of keeping him in that way, I think it would be better for Bayern Munich to let Lewandowski go in the summer because Lewandowski himself really wants to join Barcelona.
