Ahead of Sunday's Manchester derby, Manchester United fan and World's Fastest Man Usain Bolt met Manchester City striker Sergio Aguero.
And in their encounter, Bolt attempted to give the Argentine star a lesson in speed as he went through a number of drills with the striker.
However, in the comical video that can be seen above, Bolt, instead of trying to help the striker, tried to tire him out ahead of Sunday's match at the Etihad.
After the session, Bolt commented suggesting that Aguero is United's biggest threat this weekend and admitted to trying to tire out City's danger man, as he said: “Sergio’s caused United a lot of problems over the years, so I thought I’d drop in on him to see if I could tire him before the game on Sunday.
"But turns out he’s pretty fit. I have to admit I was impressed with his qualities, United definitely need to keep him quiet but I’m sure they can do that and get the three points.”
Aguero seemed to have enjoyed his meeting with Bolt, and also suggested that the sprinter is good enough to play for United, but not City.
The Argentine said: “Usain was terrible at the beginning, but I realised after a while that he was just trying to wear me out. When he started to play properly, he showed some skills though.
"He is not good enough to play for City, but I think he would have a good chance of getting into the United team.”
The training video featuring the pair was released by PUMA, as they launched their latest pair of evoSPEED 1.2 football boots this week.
Bolt will be hoping his beloved United side can overcome Aguero and City at Eastlands this weekend.
