Three-time defending champions Saudi Arabia opened their account with a win at the 2018 International Federation for Athletes with Intellectual Impairments (INAS) Football World Championships in Arvika today.
The Asian side, winners in 2006, 2010 and 2014, outclassed Russia 5-1 at the Solviksvallen stadium.
Russia were outclassed from the beginning to end against a strong team seeking to continue their domination.
European champions Poland could mount a stiff challenge in Group B, though.
They defeated Japan 2-1 in the other game in the group today.
Argentina have also won 4-2 against France in Group A.
The event is taking place in stadiums in four towns across Sweden: Tingvalla IP and Örsholmens IP in Karlstad, Sannavallen in Kristinehamn, Solviksvallen in Arvika and the Sannerudsvallen in Kil.
