Bringing in new players is mainly because they want to see some chances in areas where they hope to see changes, Madrid did not need too many changes but players who can blend into the new coaches system and that is one of the reasons Madrid had to get some new players and lay off others, the champions league this season looks like one which is going to be very intriguing and it is the second edition of this format of the Champions league and seeing how busy the transfer window has been , if Madrid must win the champions league this time they will have to earn it.
The changes needed in the Real Madrid team is the reason why they had to sign some new players, last season they were affected by injuries and a particular wing which made them concede cheap goals because that wing wasn't functioning well but right now they have good players that has occupied that position so they had to let some old players and some that are no longer needed in the team go.
Next season champions League is going to be interesting seeing how all the teams are getting ready and for Real Madrid they already know that winning the champions League next season will take a lot of good performance they should be ready o prove themselves.
