Pele on Messi, FIFA and Brazilian football
"In football, you do not always know everything. There is always something to learn.
“He can always improve his game, his movements. If I can give him advice, it's taking care of his body and looking after himself.
“The technique, he already has it. The physical aspect is the most important thing for an athlete today.
"What is missing? Not much. Maybe his heading game, the impulse and the jump.
“That's what makes us different again because I had a lot of momentum. I was going very high and I scored a lot of headed goals."
