Arsenal manager Mikel Arteta has admitted he doesn’t know how long Gabriel Jesus will be unavailable after the striker underwent knee surgery.

The 25-year-old suffered the injury during Brazil’s 1-0 defeat by Cameroon last Friday at the 2022 World Cup.

Some reports claim Jesus could be out for at least three months, but the Gunners are refusing to put a timescale on his return as yet.

When Arteta was asked about Jesus’ return date after a 3-0 win over Lyon in Dubai, he said: “No. Obviously, we know that. He needed some intervention in the knee, and we will have to take it day-by-day, week-by-week, and see where it takes us.”

Arteta has Eddie Nketiah as a backup for Jesus, while Gabriel Martinelli can also fill in at center forward if required.

The Arsenal boss was asked if he would bring in another striker in January.

He replied: “So what we can do after that, when we know a little bit about the timescale and when we can have him back, is look at the options and try to make the right decision.”
