I believe that Real Madrid will remain strong even with the farewell of Toni Kroos, it is true that it will be difficult to replace him but you will see that it will not be long and the management of Real Madrid will find a valid replacement. For me Real Madrid remains the favourite team to win the next Champions League, they have many champions in the team and a coach who was born to win the Champions League
Replacing him is not something I'm seeing any difficulties with in Madrid, they have had times they played in his absence last season and they still did well so all they will have bro do at this time will be with some adjustments where they are going to see how others are going to fit in rather in the position where he's supposed to be. This isn't undermining the fact that he was a very vital and important part of the team and is even almost irreplaceable, but with Madrid I believe they have gotten to that zenith of strength where almost no players exist will really put them off balance but them been able to make adjustments.
