Arsenal striker Gabriel Jesus says he is unable to remember playing football "without pain".
Jesus, 27, had knee surgery after sustaining an injury that ruled him out Brazil's World Cup campaign in December 2022 - missing 99 days of action.
The forward, who has made 15 Premier League starts for the Gunners this season, has suffered three further knee injuries in just over a year.
"Sometimes I feel it [my knee]," Jesus said.
"I don't remember the last time I played football without pain.
