Ryan Garcia has set his sights on a clash with Errol Spence Jr just days after his extraordinary victory over Devin Haney.

After a prolonged series of bizarre and troublesome social media posts leading to concerns surrounding his well being, Garcia entered his clash with former amateur rival Haney as a sizeable underdog.

Though he missed the 140lbs weight limit by three pounds, Garcia produced a career-best performance at the Barclays Center, scoring three knockdowns en route to a majority decision win.

The victory marked Garcia's first fight under the tutelage of Derrick James, a distinguished trainer who previously served as Spence's head coach. 

The pair worked together for more than a decade before splitting after Spence suffered the first defeat of his professional career against Terence Crawford in July. 

Earlier this week it emerged that James has filed a lawsuit against the former welterweight champion regarding his payment for last summer's superfight, alleging that he received just $250,000 despite claiming to be owed 10% of Spence's total purse which was reported to be $25million.

James is said to be seeking 'no less than' $5m in damages, for alleged fraud and breach of contract with Spence counter suing his former coach in a bid to get the complaint dismissed.

In a video posted on social media, Garcia took aim at Spence and vowed to knock the 34-year-old.

'Spence has got beef with my coach.

'What's good? Come see me. You want to sue him? I want to beat you up. [I will] knock out Errol, nice.'

Spence isn't the only fighter Garcia has clashed with on social media in recent days however.

The 25-year-old engaged in a heated exchange with Conor Benn on X, insisting he would 'fracture [Benn's] SPLEIN(sic) and then eat it' and called for the pair to fight at the O2 Arena in London.
