The Argentine footballer shared locker room with both footballers, and even he can't decide which one of them is better!

Tons of experts, fans and footballers from different eras have given their verdict on who should be considered among the best in history between Cristiano Ronaldo and Lionel Messi. But even a man that shared time with both of them on the pitch can't make up his mind.

Speaking in a conference to young children, former Manchester United and Argentina footballer Carlos Tévez shared insights on how both footballers work, adding that he can't decide which one is better since they reached greatness in this sport in different ways.

"You never saw Messi in the gym. He's used to do everything naturally, he's always on the ball and creating stunts with it. For example, he never took free kicks, and now he's making a habit of scoring great goals. That's something's he's been practicing," Tévez stated.

Then, it came to Cristiano Ronaldo, who's workout regime saw him arrivin three hours earlier than his other team-mates at Manchester United, when he shared locker rooms with Tévez.

"CR7 can stay in the gym all day, trying to be in the best shape possible to become a better version of himself on the pitch. It's his obsession. If our training began at 9:00 A.M., I'd get to the training complex at 8 and he was already there. One day, I got there at 6:00 A.M. and he was already working out," Tévez revealed.

So, there you have it. If one man that worked alongside each of these football titans can't make up his mind, why should we? All that's left for us is to enjoy their time on the pitch...
