The Argentine spoke to Mundo Deportivo and addressed a wide range of topics, including Neymar, players to watch at the 2018 FIFA World Cup, and Zinedine Zidane's departure from Real Madrid.

Messi was also asked about Ronaldo's comments after the UCL final, when his Portuguese rival revealed he could leave Los Blancos in the current transfer window.

"I do not know what went through his head or what his motives are," the Argentine told Mundo Deportivo, as cited by RealTOTAL.

"He will surely have his reasons. These are personal decisions that I cannot judge."

Messi and Ronaldo have chased each other for records ever since the latter arrived at Los Blancos in 2009.

They have shared the past 10 Ballons d'Or between them, but Ronaldo has overtaken Messi when it comes to Champions League titles after lifting his fourth in the past five years with Real last month.
