He revealed he loves nothing more than preparing to slug it out with opponents with the help of Sylvester Stallone's 'Italian Stallion'.
Alexis told The Sun: “I get motivated watching Rocky films. I used to watch them all the time as a kid, especially Rocky V.
“I remember when I was playing at Cobreloa at my beginnings, I used to watch every Rocky movie about five times in a short period.
“Rocky motivated me because I watched him working so hard.
“He drank eggs as breakfast, do you remember? I tried to do that once but I threw up! But he was so inspirational — I used to run up and down the stairs like him."
The devoted fan was even able to make a pilgrimage to the boxer's home town Philadelphia while on international duty in the summer.
He explained: “During the Copa America I got motivated by seeing the Rocky Balboa statue in the city. I actually visited it."
