Babbel writes off Bolt's A-League chances

Western Sydney Wanderers coach Markus Babbel says the Usain Bolt experiment at rival club Central Coast Mariners isn't working and he doesn't believe the Jamaican sprint legend will play in the A-League.

The former Olympic and world champion has been trialling at the Mariners for most of the past two months in a bid to earn a contract.

"For the A-League it was a fantastic period but I can't believe that he will play in the A-League," Babbel said on Friday.
