In the champions league, Real Madrid got 14 titles so far which is much more than other teams, the second team on the list is Ac Milan they got only 7 titles and they have a long way ahead to reach Real Madrid we know the Champions League is the first priority for Real Madrid and they even sometimes save some players from La Liga to have better performance in this tournament which is more important for them.
Even in the next Champions League because of the better players and potential they have, Real Madrid can have much chance to compared to other teams. Even Manchester City with Guardiola while there in their good from will have problems against Real Madrid.
https://www.uefa.com/uefachampionsleague/history/rankings/The nickname of the King of Europe is indeed not mere boasting. They have proven it by entering the final eight times since 1998, and eight times they have won. And until now, if Real Madrid had passed the semifinals and then entered the final, they would be the champions. Luckily this season Man City can defeat Real Madrid in the semifinals, otherwise Real Madrid will definitely win the 15th UCL trophy.
But whatever it is, Real Madrid this season is indeed very weak. It was clear that against Man City in the semi-finals, even in the first round, Real Madrid couldn't do much. I'm sure Real Madrid will learn from this season and now they are building a luxurious squad for next season, with the arrival of Jude and several other players this is proof that Real Madrid is serious about competing in the UCL next season.
