Gennady 'GGG' Golovkin and Saul 'Canelo' Alvarez both had to be restrained by their camps after facing off ahead of their long-awaited rematch.The two legendary fighters are set to go head-to-head once again on Saturday night after their much-debated and extremely controversial first fight, which ended in a split draw decision.In what is already being billed as a potential fight of the century, both Golovkin and Alvarez have been extremely vocal in the build-up to the clash about the other fighter, as well as how they see the fight planning out.Now, after a manic and frenetic weigh-in on Friday night, it appears some of those words and emotions may just have bubbled over slightly, with both fighters being pictured exchanging words with one another as they went face-to-face for the final time before the fight. Both fighters then had to be held back by their team as 'Canelo' appeared to be shoved backwards, and take issue with something said by either 'GGG' or a member of his entourage.Golovkin and his team have repeatedly publicly criticised Alvarez, after the fight was initially postponed due to the Mexican fighter testing positive for clenbuterol in March of 2018.Triple G's trainer Abel Sanchez also added fuel to the fire after their first bout by accusing both Canelo and his team of wrapping their fighter's hand in an illegal manner.Alvarez has long protested his innocence with regards to both claims, and has been irked by Golovkin's repeated and very public calls for boxing to be a fully clean sport - and punish those who are caught doping in a much more severe manner. So what were boxing fans saying about the weigh-in?Well, most highlighted how calm Golovkin looked compared to his opponent.

Much has also been made of the judges for the upcoming super fight, after the performance of the officials came in for ridicule and criticism after their first fight in September of last year. 

Despite two judges scoring the fight extremely closely - 114-114 and 113-115 in favour of Golovkin - judge Adalaide Byrd's scorecard of 118-110 in favour of Alvarez had many fans and pundits alike questioning the validity and reliability of the adjudicating.

Whilst the selection of judges remained a hot topic during the negotiations for the rematch, both fighters have promised the scorecards won't be needed this time around, with both looking to cement their status as the world's best with a fearsome knockout.
