Saliba joins fellow defender Gabriel, who is already out with a thigh injury sustained while playing for Brazil, in the list of injured players for the Gunners.

Arteta stated that Saliba's injury will take several days to recover from, and expressed his concerns about the timing of the injury, comparing it to another earlier this season that was also unexpected.

"I'm not going to be able to provide much information today, as we have a training session later," Arteta said.

He described Saliba's injury as a "little niggle" that will take a few days to heal.

Arteta noted that Saliba's previous injury was also unexpected and unlucky, and expressed hope that this one will also be resolved quickly.

Arsenal is chasing its first league title in over two decades, and injuries to key players like Saliba and Gabriel may impact their chances of achieving this goal.
