Real Madrid remains the most successful team in the UEFA Champions league but they really struggled for so many years in their quest to lay their hands on their tenth title popularly called LADECIMA.
Below is the dismal round of 16 performances registered by the most successful team in the world.

– 07/08: R16

When Cristiano arrived Real Madrid from Manchester United for a world record transfer fee, massive pressure and expectation were on his shoulders to alongside with his teammates deliver the LADECIMA. The first year of Cristiano was same of the same but they made 3 successive semifinal appearances before they finally won the coveted LADECIMA in the 2013/14. The team followed up the defense of their LADECIMA with a semifinal appearance which to tell was a failure. Then came the dominant years, the years they did the impossible they didn’t only win the 11th title but became the first team ever to successful defend the UCL TITLE, THEY WENT ON TO WIN THE 12TH AND 13TH TITLES.

Then Ronaldo left for Juventus for 100 million Euros …After his departure Real Madrid went back to their vomit and their round of 16 hoodoo resurfaced again. They were destroyed by the boys from AJAX BY 4 GOALS TO 1 right inside the Bernabeu AND they were consequently knocked out of the Competition on 5-3 aggregate.
After Ronaldo:
– 18/19: R16
Real Madrid lost Cristiano Ronaldo‘s incredible goals averaging more than 40 goals per season,the winning mentality that the boy from Madeira brings is awesome, that again left with him to Turin.The enviable fear factor is also missing in this present Bernabau squad.He was arguably the soul and heart of the UCL treble winning team, the last time they beat Ajax by this same 4-1 margin away in HOLLAND, Cristiano scored a wonderful hattrick.
