Real Madrid haven't changed much because their squad is still solid with lots of quality players. even Marcelo leaving didn't have any impact on the madrid squad. but in barcelona they really need to bring in quality stickers to be able to spearhead the attack and the signing of lewandowski has had a good impact for barcelona at the start of this season. even Lewandowski until the 7th round of matches earlier this season he was already listed as the temporary top scorer. so in this comparison real madrid only needed a small change at the start of the season whereas barcelona had a big change in the squad.
Real Madrid still dominance by old squad in this season like Luka Modric, Toni Kroos, Karim Benzema, Dani Carvajal have been more than 5 years ago with Real Madrid. Another new player arrived right now most completed right now Rudiger and Aurélien Tchouaméni. But Barcelona have build the new era with new player after arriving Robert Lewandowski and Raphinha drastically give positive impact for team with 5 won and 1 draw in six La Liga games until right now.
Barcelona not matter spent much money for Robert Lewandowski transfer because he has success scoring many goals in La Liga and UEFA Champion League for Barcelona in this season after get stuck last season with attacking line. Until six games Robert Lewandowski lead as La Liga top scorer with 8 goals although his competitor Karim Benzema left 5 goals from Lewandowski after missing in several match with injury.
