Arsenal striker Gabriel Jesus is ready to make his return after missing the opening games of the season due to a knee injury, manager Mikel Arteta said on Friday.

Jesus underwent a minor knee operation before the season started after sustaining an injury at the Qatar World Cup.

"It was a big blow to him, after the pre-season that he had to have another surgery, but he's looking really sharp, he trained the full week really good, so he's ready to go," the manager told reporters ahead of Saturday's game with Fulham.

When pressed on whether the Brazilian could be involved in Saturday's game, Arteta was very positive.

"He is ready to go. (From the start?) Let's see."

The Saudi Pro League window remains open longer and Arteta was asked if this is fair. "No, because it's a competitor now. That's my opinion."

Pep Guardiola is fully focussed on Manchester City's clash against Sheffield United on Sunday, assistant manager Juanma Lillo said, despite the Spanish coach being in rehabilitation after a back surgery.

Guardiola, who is recovering from the surgery in Barcelona, will not be on the touchline for City's league games against Sheffield and Fulham.

"The contact is continuous, Pep is watching Sheffield right now. What's important is his health. It doesn't keep him from being who he is. He's fully focussed on the match," Lillo told reporters ahead of Sunday's clash.

"He is telling us the surgery has been successful, his recovery has to take the necessary time."
