Madrid have built a very strong squad this season. But we have not seen the expected performance from the team. Madrid has some weaknesses in their defense. Apart from that, I do not see any weaknesses in the overall performance of the team. Real Madrid will probably not spend much money in the next transfer window. Xabi Alonso will have to build his match strategy with this squad. Madrid will undoubtedly want to dominate both the Champions League and La Liga next season.
If you want a club with a good squad that should be Madrid and people predicted that for sure Madrid is going to take the lead and there expectations were cut short this is why you don't depend to much on a particular club when it comes to football. The transfer window will be actually very busy, because a lot of clubs need to work on there club and this is all part of the reason why every club will be very active because they want to improve so everyone will be busy.
