Watch: When Eddy Reynoso advised Canelo Alvarez to stop hunting for the KO against 'too strong' Gennady Golovkin
Canelo Alvarez has fought some of the best fighters in the world. However, the biggest challenge of the Mexican's boxing career came when he fought the Kazakh monster Gennady Golovkin, twice.
In the second fight, Canelo Alvarez's trainer warned the Mexican champion to stop trying to knock Golovkin out.
The corner audio from the 11th round proved that Reynoso was aware of Gennady Golovkin's granite chin and superior physical strength.
His toughness proved to be too much for Canelo, as the current unified super-middleweight champion failed to secure his signature knockout.
Reynoso was heard saying:
"[Move your waist, don't risk it my son! Don't risk trading punches like dumb, Saul! Are you listening?...I don't want you to..you can't knock him out! Don't try to knock him out cabron! He's too strong!"

Reynoso's panic stemmed from the round before, when Canelo Alvarez ate a massive right hand from Golovkin, who supposedly rocked the Mexican champion.
