Saka was kicked painfully in the leg in Monday’s FA Cup third round victory at Oxford and was replaced by Emile Smith Rowe in the closing stages.
But asked on Friday afternoon if Saka should be okay with facing fierce rivals Tottenham, manager Mikel Arteta told reporters: “I think so, yes.”
Arsenal have an almost fully fit squad for their short trip to Spurs, with Gabriel Jesus (knee) and Reiss Nelson (hamstring) their only absentees.
Key man Jesus has been out since early December after undergoing post-World Cup knee surgery with Brazil and, while he is recovering well, the striker still has some way to go.
“The update is that he’s progressing very well,” said Arteta, who has seen Eddie Nketiah stepping up to the plate in Jesus’ absence. “He works really hard.
“He’s in the right place in his recovery compared to the time we’ve set for him, but he’s still a bit off to be fair.”
Predicted Arsenal XI (4-3-3): Ramsdale; White, Saliba, Gabriel, Zinchenko; Odegaard, Partey, Xhaka; Saka, Nketiah, Martinelli.
