Real madrid didn't make much signings as Barcelona this season, Ancelotti did mention that he was satisfied with the players he had already and with few additions he was ready to kick start the season, those statements he made turned out to be right and proves he knows what he is doing. The current players in the team have shown satisfactory performances this season. Barcelona also have shown improvement this season afteraki g several signings this summer and before. As the season grows old we will see how well both teams have improved and who is the favourite to win the trophy.
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.
