Google Inc. and other internet service providers have turned over confidential user information to a Portuguese soccer team that may help it identify anonymous bloggers who have written about allegations of wrongdoing against the team.

The information was turned over as part of a lawsuit filed by the team, the Lisbon-based Benfica, earlier this year in United States District Court in California as part of an effort to stop the bloggers.

Benfica, the serial national champion, has been battling a tide of leaked information for much of the past year that has cast a negative shadow over it . The leaks have been drip-fed onto a specially created website since December, producing sensational headlines and leading to a crisis within a club that counts some of the country’s most important politicians and business figures as members.

However, Benfica was unable to stop the leaks through Portugal’s legal system. So the club, a two-time European champion, turned in April to California’s courts. It issued subpoenas to Google and a handful of other companies that own the platforms used by the bloggers.
