The 19-year old academy graduate has played 29 games for the Gunners this season.
Saka might feel the sense of burnout in his second full season for the North London club.
He has scored six goals and made five assists in this current campaign.
“I think he’s in a great moment, he’s full of confidence,” Arteta has told reporters.
“He’s been really important in recent results. His form is probably the highest that it’s been since I’ve been here and he’s been really consistent. He needs to keep going and (we need to) be wise with him because at the moment he’s a big part of the team.
“I think we have to protect him and keep the extractions where they should be, but I’m not going to put a brake on his development or how much he can do week in, week out.
“We have to support him and give him the best possible advice all the time, and then manage his minutes so he can maintain this level.
“It is (difficult) at the moment because he’s been a real threat. He’s involved in a lot of goals all the time and his consistent performances make him a starter obviously. So it’s a fine balance, but at the same time he’s 19 years old and we have to protect him.”
