Tierney, as well as his compatriot Ryan Christie, were instructed to self-quarantine for 14 days after their Scotland teammate Stuart Armstrong tested positive for coronavirus while on international duty.
Both Tierney and Christie returned the tests negative and have insisted that they meet social distancing guidelines.
But Scottish health authorities identified the two players, as well as two members of the Scottish backroom staff, as close contacts of Armstrong.
Tierney missed all three Scotland games and told the Arsenal website he was “very disappointed and frustrated to be in this situation.”
But, as talks continue to free Tierney from his period of self-isolation, Arteta is hopeful that the full-back can perform at Etihad Stadium this weekend.
“We are still in talks with the authorities,” said the Arsenal manager. “This becomes very complicated when you send players overseas and obviously lose control.
“Some authorities have different regulations than the current ones in the Premier League.”
The number of positive tests for Covid-19 has risen during the international hiatus, with the Irish team affected by a series of forced withdrawals, while Portugal’s captain Cristiano Ronaldo was also a confirmed case of coronavirus.
Arteta believes it is important to keep international matches on the schedule with big tournaments to come, but he wants consistency in the rules.
“What we are asking is that we try to unify those protocols, rules to try to create a safe environment for our players,” he said.
“But we also protect the clubs because obviously the impact of having some players out when we resume the Premier League is really great.”
Arteta also declined to be drawn on whether deadline-day signing Thomas Partey will make his Manchester City debut, given that he has yet to train with his teammates.
He also suggested that William Saliba would not go on loan to the championship after the club had looked into the possibility of taking the teenage defender some football out of the club.
