Saka took a kick during Monday’s FA Cup third round victory at Oxford and was taken off for Emile Smith Rowe in the closing stages.
But asked on Friday afternoon if Saka should be okay to face Tottenham on Sunday, Arteta said: “I think so, yeah.”
Arsenal have a near fully-fit squad for their trip to Tottenham, with Gabriel Jesus (knee) and Reiss Nelson their only absentees (hamstring).
Jesus has been out since the start of December after undergoing knee surgery and, while he is recovering well, the striker still has a way to go.
“The update is that he is progressing really well,” said Arteta. “He is working really hard.
“He is in the right place in his recovery regarding to the time that we set for him, but he’s still a bit far to be fair.”
Arsenal likely XI (4-3-3): Ramsdale; White, Saliba, Gabriel, Zinchenko; Odegaard, Partey, Xhaka; Saka, Nketiah, Martinelli.
