LONDON (Reuters) - Manchester City âs Argentine striker Sergio Aguero  has broken a rib in a road accident in the Netherlands and will miss Saturdayâs Premier League game at Chelsea with World Cup qualifiers also doubtful.
Manager Pep Guardiola  speaking to reporters before  Aguero  had seen club doctors  said the player was definitely out of Saturdayâs game between league leaders City and champions Chelsea.
He also cast doubt on  Aguero  travelling to Argentina for World Cup qualifiers next month.
âExactly how many days he will be off  I donât know right now â he said  adding that he had âno problemâ with  Aguero  being in Amsterdam.

 Aguero  had earlier posted a picture of  himself  on  his  Instagram account seated in the back of a car thanking Colombian singer Maluma  who was also in the photo  for the invitation.
City are level on 16 points with Manchester United at the top of the table with Chelsea in third place on 13  and  Aguero  is one goal away from equalling Eric Brooksâ all-time club record of 177 goals in all competitions.
The international break follows the weekendâs Premier League matches with  Aguero  in Argentinaâs squad for their last two World Cup qualifiers against Peru and Ecuador on Oct. 5 and 10.

Kaitlyn Murphy   a 31-year-old resident was arrested earlier this week on felony defraud charges after she admitted to using glass to get out of paying for her food  a trick the woman claims to have learned from someone she knew in rehab.
 Murphy  confessed that she would carry glass in her purse when she went out to eat and would sprinkle it over her food. She even intentionally cut her mouth by chewing the glass to make her story more realistic.
The police reported that  Murphy  had visited eleven restaurants in Stuart  FL  from September 15 to September 26 â claiming to find glass in her food âafter eating most of her meals â Local 10 News reports.
After  Murphy  reported the hazard  the restaurants would either eat the cost of the meal  or offer gift cards and free food.
The police were eventually tipped off about  Murphy âs crime spree after restaurants started describing the same woman on social media  coming into their establishments and making the same claims.
The pressure of social media forced  Murphy  to turn herself in  where police found more glass shards in her purse.
In total  the police say  Murphy  cost restaurants hundreds of dollars in comped meals  gift cards  lost tips and lost food  as well as damaged the reputation of some servers and restaurants.
 Murphy  originally claimed that  she  did it because  she  couldnât afford the food  but later a manager said  Murphy  confessed  she  did it for the adrenaline rush â a high  she  was searching for after  she  had quit drugs and alcohol.
Just before  her  arrest   Murphy  was hired to work as a server in the area.

Embattled Republican Party chairman Michael Steele announced Monday that he will seek a second term despite a rocky two years marked by allegations of financial mismanagement and frequent verbal gaffes.
 After weighing a decision for weeks as challengers lined up  Steele alerted the 168-member Republican National Committee during an evening conference call that he would run  according to participants listening. They spoke on the condition of anonymity because the call was private.
 Steele's troubled first term expires in January  and the committee must then vote on who should run the party's national operations during the 2012 presidential election cycle.
 A former Maryland lieutenant governor  Steele was chosen to run the party in January 2009. He became the first black national chairman in the Republican Party's history just shy of three months after the nation elected a Democrat as the first African-American president.
 Steele was considered an outsider because he wasn't part of the RNC's clubby environment. His brash style and unconventional ways irked establishment Republicans from the outset. Questions about his financial management of the RNC followed.
 Republican victories up and down the ballot in November didn't quiet Steele's critics. Complaints about Steele's stewardship of the party's national operations only mounted. And he has watched his once strong support within the RNC rank and file all but evaporate as Republican leaders on Capitol Hill and in states across the country signaled they desired new leadership.
 No less than a half dozen Republicans are weighing challenges to Steele or have launched candidacies. The two latest to formally announce bids are Maria Cino  a New York native who served in the Bush administration and planned the party's 2008 nominating convention  and Gentry Collins  who headed the RNC's political department under Steele.
 Others in the mix include: Saul Anuzis  a committeeman from Michigan who lost to Steele in the 2009 chairman's race; Reince Priebus  the Wisconsin Republican chairman  and Ann Wagner  a former Missouri state Republican chair and a former ambassador.
