Fresh starts for troubled Argentine pair

River Plate are set to welcome back two old favourites as they attempt to improve on their dismal showing last year while referees will use an aerosol spray to try and stop defensive walls creeping forward at free kicks.

The credit crunch appears to have favoured the championship with only a few players departing for Europe, notably Boca Juniors midfielder Jesus Datolo who has joined Italian Serie A club Napoli.

Racing Club, Argentina's fifth most successful club in terms of domestic titles, emerged from 10 years of bankruptcy in December before their 5,000-odd members voted in Rodolfo Molina as the club's first president since 1999.

Only one of Racing's seven national titles has been won since 1966 and the club has employed 16 coaches in the last decade.

Newell's Old Boys go into the championship under new president Guillermo Lorente after he won December's election against Eduardo Lopez, who had ruled the club for 14 controversial years.

The situation is tense and last month a gang of around 30 armed men, suspected of belonging to a faction of the club's own supporters, invaded the club's headquarters, threatening staff and members.
