Arsenal star Mesut Ozil continues to suffer with the back injuries that plagued him for much of the past season.

The German international missed the final three club matches of the campaign with the back problem, which he had been nursing on and off for several months.

Ozil’s injury did not stop Joachim Low from naming the playmaker in his World Cup squad but the 29-year-old has required ongoing treatment during the pre-tournament training camp in south Tyrol.

He is not, however, expected to miss any of Germany’s defence of the title they won in 2014 and has taken part in training with his team-mates.

Low’s assistant Thomas Schneider said of Ozil: “He’s always receiving treatment, but is completely resilient.

“We expect him to push himself in the coming days and weeks leading up to the start of the tournament, and we’re confident he will manage.”

Germany’s World Cup begins against Mexico on June 17, with warm-up friendlies against Austria and Saudi Arabia still to come.
