When it comes to sprinting, nobody's voice carries more authority than Usain Bolt's.
However, the world's fastest man has now turned his attention to his favourite football team, Manchester United, and has a message for new manager David Moyes.
Bolt's not happy about the lack of transfer activity at Old Trafford—going into the final day of the summer window, United have not made a single major signing—and has taken to Instagram to voice his unhappiness.
"I'm a big fan of Manchester United," Bolt opens.
"Dave Moyes, we need a creative midfielder, one that can pass and create opportunities, right now. More control. Serious face."
He's clearly given the video a bit of time and thought, as well. When he says United require more control, he throws in a cutaway to two Playstation controllers.
Will Moyes listen? That will be half the fun of watching on deadline day—there are certainly no shortage of transfer rumours swirling around the Red Devils as the window closes.
If all else fails, maybe Usain could be the answer to Moyes' prayers—after all, he's previously suggested he would be interested in a trial, back when Sir Alex Ferguson was in charge.
I would not take up the challenge if I didn't think I was good enough. I am a very accomplished player and know I could make a difference. People think I am joking. But if Alex Ferguson called me up and said, ‘OK let's do this, come and have a trial', it would be impossible for me to say no.
