I think Real Madrid doesn't react much to this transfer. Lewandowski moved to Barcelona, yes, Barcelona fought for a very long time for this transfer, but so far it does not mean anything, neither for Real nor for Barcelona itself. Wait until the season starts and Lewandowski starts scoring goals for Barcelona. I am still very skeptical about this transfer, Barcelona are betting too much on Lewandowski, this is not right.
Why are you skeptical about this transfer? Is there any doubt that Lewandowski is a talented and experienced player? However, having played in the Bundesliga for a long time, Lewandowski may need some time to adapt to the La Liga gameplay. But since he is experienced, he probably knows well how to adapt to a new team. And the coach of Barcelona now is Xavi. I think he can stabilize the team well.
