Messi has long been viewed as one of the best ever to play the sport and his starring role in Argentina's World Cup success in Qatar last year has convinced many that he is the greatest football player of all time.
The seven-time Ballon d'Or winner's exploits have not impressed famous streamer Speed, however, as he revealed he is strictly pro-Cristiano Ronaldo and full of hate for Messi.
"Messi like really might be the worst football player in the world!" Speed shouted after barking like a dog when he was shown a Messi jersey in his appearance on the latest episode of Kit Collector.
"Don't ever show me that kit, man. What's wrong with you?"
Asked why he holds such resentment towards Messi, he added: "Okay. You want me to be completely honest? Messi is like, he just only can dribble. The only thing he can do is just dribble. I'll give him that. I don't like Messi but the only thing he can do is dribble.
"Messi has like a three-star skill move on FIFA, bro. Guess what Ronaldo's got - five stars. Messi's not a skill player, all he can do because he's like 5'3 the only thing he can do is dribble.
"You know [Alejandro Garnacho] from Manchester United? I think he's better than Messi. He can do skill moves... He's not a good player, simple as that."
