Arsenal full back Hector Bellerin could miss the start of the 2019/20 Premier League season.
The Spanish star is experiencing problems with a knee injury that he suffered in January.
He underwent an operation at the time, but was expected to recover in six to nine months.
But the Evening Standard indicates he will not be back in time for pre-season, which means he could miss one to three months of the new season.
The Gunners do not want to rush the 24-year-old as they fear a re-injury.
