Allen and His Team Fire Back
Brendan Allen did not stay silent after Strickland’s harsh words. He revealed that his entire training camp had a strong reaction to Strickland’s pre-fight trash talk.
According to Allen, the words coming from Strickland are nothing more than empty threats. He and his training partner Alan Nascimento both stated that Strickland’s trash talk is “all talk” with no substance behind it.
Nascimento backed up Allen’s assessment of the situation. The two fighters dismissed Strickland’s comments as typical pre-fight hype that doesn’t match reality.
Allen explained that helping Chimaev prepare was a professional decision based on his training relationships. He trains at the same gym as Chimaev and considers it normal practice to help teammates prepare for fights.
Strickland’s Reputation for Controversy
Strickland is known throughout the UFC for his outspoken personality and controversial statements. He rarely filters his opinions about other fighters or situations in the sport.
The former champion has built a reputation for intense trash talk leading up to his fights. His comments often cross lines that other fighters avoid, which generates both criticism and attention.
Strickland’s upcoming fight with Chimaev represents a major test for both fighters. Chimaev has been viewed as one of the most dangerous rising stars in the middleweight division.
The Russian-born Swedish fighter has demolished most of his opponents with dominant performances. His wrestling and grappling skills have proven difficult for middleweights to handle.
Strickland will need to overcome Chimaev’s strengths while dealing with the fact that his fellow middleweight helped prepare his opponent. The mental aspect of knowing Allen worked with Chimaev could add another layer to the fight.
Allen defended his choice by pointing out that fighters help training partners all the time. He suggested that Strickland’s reaction was overblown and fueled by his tendency to create drama.
The public exchange between Strickland and Allen has added another storyline to the Strickland-Chimaev fight buildup. Fans on social media have taken sides, with some supporting Strickland’s anger and others agreeing with Allen’s decision.
Neither fighter has indicated that the verbal battle will end anytime soon. Strickland continues to express his frustration with Allen’s decision to help Chimaev, while Allen maintains that his choice was appropriate and professional.
