The argument is going on, it will run. Even they will not stop after two retirement. Who is the best Lionel Messi or Cristiano Ronaldo? There is no perfect answer to this question. But one can get an idea from the statistics. Ronaldo is back in the stats after the start of Messi-Ronaldo's race in Spain. 
Ronaldo, who left Manchester United, walked to Real Madrid in 2009. The Portuguese star has got the chance to win 36 trophies in this nine year.
But he has won 15 titles (assuming he can not win La Liga this year).
At the same time, Messi has won 22 titles for Barça That means Ronaldo is back in the trophy with eight trophies in Spain. But this season, there are two antagonists getting the chance to increase the number of titles. Barca's La Liga wins almost sure. On the other hand, Real has emerged in the semifinals of the Champions League
In this new season, Real has to win the title '16' to win the semifinal berth of the tournament. Ronaldo is lagging behind with the exception of Messi, who won the La Liga title this season. Ronaldo has won La Liga for two seasons (11-12, 16-17) for Real. Messi won La Liga five times in the same period. A little wrong, the sixth title is obviously won!
However, on the European Sera (Champions League) season, Messi is lagging behind his antagonist in this season. Messi has won the Champions League Twenty20 twice.
Ronaldo won three times. Messi is ahead in the Copa del Rey and Spanish Super Cup since 2009
Barca has won two of these five-times matches. Ronaldo won twice. Both have won three times the FIFA Club World Cup and the European Super Cup.
