Bayern Munich's Arjen Robben is doubtful for the Bundesliga season-opener against VfL Wolfsburg due to a lack of match practice, coach Pep Guardiola said Thursday.

The Dutchman joined the team later than some of his team mates after the Netherlands' run to the World Cup third place last month and did not play for the Bavarians in the German Super and German Cup last week.

Bayern, domestic double champions last season, have several big name absences with Bastian Schweinsteiger, Franck Ribery and Javi Martinez among them.

Guardiola, in his second season in charge of the German record champions, said despite the injury absences that could make it hard for them in the first few months of the league, the title still remained their top goal.

Bayern won the league title in record time last season, becoming the first team to secure it in March.
