Adu is heading to France

American soccer teenager Freddy Adu will move from Portugal's Benfica to play with Monaco next season in the French league.

Benfica said late Monday that the 19-year-old midfielder will join Monaco on a seasonlong loan, and the French club then will have the option of signing him to a permanent contract.

Adu joined Benfica in July last year but started only two matches, scoring five goals in 21 appearances as the team finished fifth in the Portuguese league, and had three different coaches in an unsettled season.

He will play with the U.S. team at the Beijing Olympics next month and is then expected to join Monaco, which finished 12th in the French league last season.

More Ronaldo saga

Manchester United manager Alex Ferguson warned Cristiano Ronaldo that moving to Real Madrid would be "the worst thing" for his career.

The Portuguese winger again refused to commit himself to the Red Devils over the weekend, but Ferguson is confident he will stay at Old Trafford after scoring 42 goals last season.

"After the Champions League final, he was the happiest boy in the world," Ferguson said Monday from Man United's tour of South Africa. "I think he knows genuinely where the best club is to be at, and that is Manchester United.

"I honestly believe that the worst thing he could do is go to Real Madrid. He's 23 years old, he is at the right club, he is at a fantastic club and there should not be any need to think in any other way."

United told Ronaldo he will not be sold or offered a new contract with a pay rise to match any offer from the Spanish champions.

Instead of increasing Ronaldo's weekly pay of $240,000, United wants him to display commitment and loyalty.

"He signed a five-year contract last year, and he still has four years left," Ferguson said. "That's definite — I know that. I've seen his signature.

"Young lads can be twisted by the talk of money and moves that are happening all the time in modern-day football."

Ronaldo, who is sidelined until at least October after recently undergoing surgery on his right ankle, is not on the tour to South Africa. United played the Orlando Pirates on Tuesday in Durban.

Postponed again

Tuesday night's soccer match between D.C. United and the Houston Dynamo has been postponed because of a power outage. The game has been rescheduled for Wednesday at 5:30 p.m. MDT.

The match was originally supposed to be played in June but was postponed because of heavy rain, making the surface unplayable.

Robinho to miss Games

Robinho was dropped from the Brazilian Olympic team on Monday after Real Madrid said a medical examination discovered the striker has a groin injury.

The Brazilian football confederation criticized the Spanish club and said the decision was a "disrespect to the entity, to football and to Brazilian fans."

Brazil physiotherapist Luiz Alberto Rosan said he knew of Robinho's injury but that the player would have had time to heal before the Olympic tournament.

The Spanish powerhouse said the injury was discovered when the player arrived for a medical examination and light training along with most of the club's squad.

"The best thing for the player is to complete preseason training with the squad where he will be given rehabilitation tailored to his injury and where he will be under constant supervision," the club said.

Essien staying put

Chelsea midfielder Michael Essien signed a new five-year contract through 2013, becoming the third player in the past week to extend his stay at the Premier League club.

Essien, 25, has scored 14 goals in 143 games since joining from Lyon for 24.4 million pounds ($49 million) in 2005. Financial terms of the contract weren't disclosed.

"I have not been here long, but it is clear to me that Michael Essien is one of the best midfield players in the world," Chelsea manager Luiz Felipe Scolari, who took over July 1, said on the club's Web site. "I have always admired him, and it is good news for me and for Chelsea that he signs for so long."
