"It'll be difficult for some to stay on". Remaining at the top spot is Carlos Tevez, who plays for Chinese Super League outfit, Shanghai Shenhua raking in R10 million per week.
He also insisted he is happy with Valverde's rotation policy.
"But I think that this time away from the national team has done him good, now he is seeing things in a different light".
Next year's World Cup may be one last chance for the 30-year-old Messi to win a major trophy with Argentina and the Barcelona forward says they need to make changes in order to overcome more fancied countries.
"Of course, it is tough being a sub, but I have come to understand it is for the best".
By the time that contract expires, Messi will be 34 years old and potentially considering retirement.
"We were worthy of winning them because, without having played well, we had the clearest [chances] - both in the World Cup and the Copas America".
Messi said: "Mascherano? I'm not going to tell you what he told me, but I'll understand if he leaves, he wants to play more".
"I would have to review them to see what we did wrong so we didn't them". Messi, however, believes they should have celebrated at least two victories. Maybe the Argentine knows that a fear of failure can ignite Argentine spirits and disappearing from the national setup is a reality that is very much real. "People want results and, if they don't get results, they want new faces".
"Pipa has suffered a lot from criticism and we have talked about it a lot of times", Messi said.
"And a part of that doubt is due to the way the country is at the moment", added Messi.
"Bench role? It's hard for me not to play or to be subbed off, but I realised and understood that it was for the best".
