Cristiano Ronaldo and Lionel Messi both had been on four Champions League title teams–until Ronaldo's Real Madrid captured the 2018 title.
Ronaldo won his first Champions League title with Manchester United in 2008. His next one didn't come for six years, but in 2014 with Real Madrid, Ronaldo got to experience winning the Champions League for a second time. Real Madrid claimed the title again in 2016, 2017 and now 2018 to give Ronaldo five for his career.
Messi's first Champions League title came in 2006 with Barcelona. However, Messi did not play in the Champions League final that year. His second came in 2009 and the third in 2011. His most recent Champions League title came in 2015.
With Real Madrid making it four titles in five years, Ronaldo has become the first player with five UEFA Champions League titles.
