2009–10 Argentine Primera División season
The 2009–10 Primera División season was the 119th season of top-flight professional football in Argentina. A total of 20 teams competed in the season, which started on 21 August 2009 and ended on 23 May 2010.
Changes from 2008–09
The major changes for this season apply to international qualification. For the 2010 Copa Libertadores, an aggregate table of the two tournaments held in 2009 will be taken into account, instead of an average of the past three tournaments. For the 2010 Copa Sudamericana, River Plate and Boca Juniors will no longer be invited without merit. Their open berths will be up for qualification to any team, including themselves.On 21 August, the Argentine Football Association revoked the television broadcasting contract with TyC in the hopes of increasing revenue to help the financially struggling clubs. On 18 August, the AFA and the Government of Argentina struck a deal to broadcast the season for free on non-cable channels, which allowed the season to start on the 21st.
