Arteta is acutely aware of the threat of his team sliding back into their bad old ways after their recent brief recovery.
The Sun says he has made it his mission to keep delivering brutal home truths to his underperforming superstars.
Arteta was genuinely shocked by his team's dreadful first-half performance during Monday's 1-0 FA Cup win against Leeds.
And he did not hold back during a brutal half-time inquisition when he accused the players of ignoring his pre-match instructions.
Now he believes the only way to keep his stars on their toes is by constantly questioning their desire and commitment.
