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.
I have no doubt that Lewandowski will make a big contribution in his first season but I am a little surprised by what Barcelona are doing in this transfer market, they continue to bring in players who play as strikers while they already have a lot of players who play as strikers. but that's how an unstable team wants to improve, they do a lot for the best results.
whereas Real Madrid didn't do much because they still had the best squad that could win Europe last season, maybe that's the reason they are not active in the hunt for players in this transfer market.
