Robert Lewandowski's arrival would affect Barcelona very positively in the coming season. I know that they already had Aubameyang but I still thought that they should have signed a top striker to compete harder in the La Liga and the Champions League both. Real Madrid had better get ready for a tough challenge this time. We still don't know what transfers we will see as there is a long time period until the end of the transfer window. These transfers can play a key role for both teams.
