Lionel Messi, Christiano Ronaldo and Neymar Jr do not need any introduction as they're amongst the world's most talented, popular, sorth after and best football players. In saying so, am going to dive straight to the answer.
Lionel messi has a record total of 5 ballon d'Or trophies, 4 of which he won consecutively and has also won a record of 5 European golden shoes. Messi has won 9 La Liga titles, 6 Copa del Ray, 4 UEFA Championship League and a couple other titles putting his trophies at a total of 32.
Christiano Ronaldo also has a record of 5 ballon d'Or trophies. His recorded to be the first player ever to win 4 European golden boots. Ronaldo has won 5 UEFA Champions league, 5 League titles and 1 UEFA European championship. His total trophies are a total of 26 trophies.
Neymar Jr has more honors than both Messi and Ronaldo given his long football career with many clubs which he started playing at a very young age. What Neymar lacks are the heavy weight trophies which Messi and Ronaldo have. That's the reason why he ranks third on number of trophies in comparison to Messi and Ronaldo. Am not quiet certain of his total number of trophies. But here's a few of them:
Neymar Jr has won 6 Copa series titles, 2 La Liga, 3 Copa del Rey, 1 supercop de Espania, 1 UEFA Champions league, 1 FIFA Club World Cup and four France titles including 1 Ligue 1 and Coupe de France. He also has 3 Youth trophies and 1 FIFA Confederations Cup title.
