Bolt helps Ronaldo go faster for longer.

Usain Bolt, the world's fastest man, has been offering running tips to FIFA World Player of
the Year Cristiano Ronaldo.
The Jamaican, who claimed both the 100 and 200-metre world records at the
2008 Beijing
Olympics, is set to attend
the Red Devils' league clash with Arsenal on Saturday and - in all
likelihood - watch Sir Alex Ferguson's side gain the single point needed to
win an 18th English title.
And the 22-year-old will also appear on the pitch at half-time to present the club's Player of the Year prize.
"I want to run on the pitch and score in the net if they let me," he said.
"It will be something for me to have pictures of. Who knows, maybe I can be a Man U player in the future."
During United's training session on Friday, Bolt took the
opportunity to advise Ronaldo on how to adjust and improve his running
technique, in order to prevent him from tumbling to the ground time and
again.
"I explained to him a few things about when he is running and
reaches top speed he starts to tip over, he always does that," he said.
"I let him know if he brings his foot on the centre of gravity, or
even in front of him, it will be much easier. He will be much better
and he will go faster for longer.
"Because he's so fast they keep pushing him around, he needs to be more aggressive, [then] they will leave him alone."
