BOSTON – Soccer phenom Freddy Adu received his high school diploma last Friday, but the 14-year-old D.C. United forward says his soccer education has just begun.

The Adu road show comes to Gillette Stadium for the first time Saturday night when the New England Revolution host United. Interest in the teenage star, who turned down offers from top European clubs to sign with Major League Soccer, has boosted attendance wherever he plays.

“I’m not here to be an OK player,” Adu said Wednesday in a conference call. “I want to be a great player in MLS, and one that people can look up to. I want to improve every aspect of my game.”

Adu signed a six-year contract with MLS last fall and debuted last month, becoming the youngest player in a major American sports league in more than 100 years. He has played in all nine of United’s games and scored two goals. He’ll turn 15 on June 2.

Adu, who gets rides to and from practice from his mother, has shown flashes of brilliance, such as his goal last week against Los Angeles on a 16-yard shot with his left foot after a curling run past defenders. It took about five games for the 5-foot-8, 145-pound Adu to get comfortable on the field.

“I’m still getting pushed off the ball, but not as much as I used to,” said Adu, who was born in Ghana and moved to the United States in 1997 when his mother won an immigration lottery.

To counter physical play, he’s worked on better positioning and movement off the ball.

“After that, I just chilled,” Adu said. “Now, I’m myself again. I’m ready to rock and roll. As time goes on, I’ll keep getting better.”

United coach Peter Nowak will announce his lineup Friday. Adu has been in and out of the starting lineup.

“What we’re looking for right now is consistency,” Nowak said. “I’m very impressed with his work ethic. He matured pretty fast. Day in and day out, we want to make things better.”

United (2-4-3) has averaged more than 25,000 fans on the road. The other nine MLS teams average attendance is about 15,000.

Revolution officials expect to sell up to 20,000 tickets for Saturday’s game, team spokeswoman Erin O’Brien said. In three home games the Revolution (1-3-3) have averaged 13,500.

New England coach Steve Nicol said interest in Adu is “good for the game.” But on the field, Revolution defenders aren’t making special plans to stop the teenager.

“We’re going to treat him like everybody else,” Nicol said. “We don’t want players running at us, and obviously running with the ball is one of Freddy’s strengths.”

Adu graduated Friday from the Edison Academy in Bradenton, Fla. He completed his studies through an accelerated program associated with Bradenton’s IMG Academy, where he lived for two years while training with U.S. national youth teams.

He hopes to play for the U.S. national team someday, and has an eye on Europe as well. There are contract provisions to let him to leave before the six-year MLS contract expires, he said. Manchester United and Inter Milan were among top clubs that expressed interest before he signed with MLS.

“I do have aspirations to play in Europe, everyone does,” he said, adding that there’s no timetable to do so. “When the time comes I’ll exercise my options.”

For now, he’s enjoying his mom’s cooking, mostly African food, and typical teenage pursuits.

“I love to play video games and hang out with friends, and go to the mall,” he said.

As his popularity has grown, so have crowds of teenagers – mostly girls – at the malls.

“I’m not complaining,” he said.
