The former Manchester United striker played with Ronaldo at Old Trafford and has represented Argentina alongside Messi
The 34-year-old, now back at boyhood club Boca Juniors in Argentina, has trained and played with both stars.
Tevez was team-mates with Ronaldo at Manchester Untied and has represented Argentina alongside Messi.
Explaining what both do behind closed doors in training, it's clear to see there's a major difference.
"It is all natural to him, but on penalties he trained: first he did not take them and now he shoots them all at the corner."
On former United team-mate Ronaldo, he revealed: "Cristiano always stopped in the gym after training: for him it is an obsession and, being the best in everything, he always arrived at work early.
"When the training was set for 9 in the morning I arrived at 8 and he was already there.
"Even if I arrived at 7.30 he was already there.
"I began to ask myself, ‘How can I get rid of this guy?’ So one day I arrived at 6 but he was already there! Sleepy, but he was there."
"Lionel Messi, I never saw him in the gym," he told the Argentina media . "I’ve never seen him train in the stops or do technical exercises.
