Ancelotti has proven it last season when they also lost some of their best pillars. Real Madrid won the Champions League and La Liga titles thanks to the good performance of its players, as well as Ancelotti's expertise in concocting the right strategy. But can you guarantee that they can always maintain that good performance without their best players? Even if they could, it would be really difficult.
Ancelotti is a good Manager no doubt and he is not the one playing all he can do is instruct, the performance is still going to be players'. Currently,he's doing well but the players aren't not all though and when I mean they aren't playing well, I'm not saying the squad but instead the way they are relating and feeding each other on field. The injured players are returning at the moment , likes of camavinga, Bellingham.....there was just some slight change even with the new returns because with their squad Barcelona should be competing with their goals , now cavajal is injured and it definitely not returning this year, a central back(D.Alaba) player will also join the team back by November.We should just wait for November and let's see how the performance turns , atleast there's just only a RB out for the year...
