MADRID (AFP) - Ousmane Dembele's full La Liga debut with Barcelona following a €105 million (S$160 million) move from Borussia Dortmund lasted just 29 minutes as the Frenchman pulled up with a hamstring injury.

"Dembele has a hamstring injury in his left leg, more tests are needed to find out the extent of the injury," Barcelona said via the club's Twitter account.

The 20-year-old missed most of pre-season as he went on strike from training at Dortmund in an attempt to force through his move to the Camp Nou.

Barca's miserable first 45 minutes at the Alfonso Perez Coliseum was rounded off by Gaku Shibasaki's sensational volley to give Getafe a shock half-time lead.
