Injured midfielder Andres Iniesta remains doubtful for Spain's opening World Cup match after training alone during the European champion's first practice in South Africa.

Iniesta ran individual drills with one of the team's physiotherapists at the North West University sports complex in Potchefstroom, where the team is based for the tournament.

Spain was the last of the 32 teams to arrive at the tournament and was welcomed Friday with a warm reception from locals.

Coach Vicente del Bosque put the rest of his 23-man squad through an up-tempo session following its overnight flight. Fernando Torres took part with his right knee heavily bandaged as he recovers from surgery.

Spain begins play Wednesday against Switzerland.
