Capello: I tried to sign Barcelona's Messi for Juventus
Messi struck five goals in victory over Bayer Leverkusen last week.
"I do have a regret, as I faced Barcelona in a friendly with Juve and Messi was just over 16 years old. He had some problems registering the contract and I asked Frank Rijkaard to loan him to me for a year, so I could help him to grow. The response was negative, a real shame," said Capello.
