The Gunners striker came off the bench in the second half to score two quick-fire goals to help Arsenal secure a 3-1 win over Leicester City at The Emirates on Monday night.
Aubameyang netted four Premier League goals in 57 minutes of top-flight football after the Gabon international was a substitute in a 5-1 win at Fulham before the international break.
The 29-year-old centre-forward has netted eight times in 10 games in all competitions so far this season, although Aubameyang has come on as a substitute in two of those appearances.
Unai Emery initially didn’t hesitate to use Aubameyang alongside Alexandre Lacazette in the same XI, something which his predecessor Arsene Wenger appeared reluctant to try.
However, the Spanish head coach has preferred to start Lacazette in a lone striker role with an impressive attacking supporting cast, including Mesut Ozil and Henrikh Mkhitaryan.
But former Liverpool FC defender Carragher believes Emery should accommodate Aubameyang in his starting side, even if it means playing the African striker on the wing.
“He has to start,” Carragher told Sky Sports’ Monday Night Football.
“There will always be that thing whether Aubameyang and Lacazette can play in the same team. He has almost played in that Salah position on the wing.
“I think it is a must Aubameyang plays. Arsenal look much better when he plays.”
Aubameyang moved to Arsenal in a £58m deal from Bundesliga outfit Borussia Dortmund in the January transfer window to become the final signing of the Wenger era.
The former AC Milan forward has netted 18 goals in 24 games in all competitions in an incredible start to his Arsenal career so far.
Aubamayang arrived at Arsenal from Dortmund having built a big reputation in the Bundesliga after scoring 141 goals in 218 games during his five seasons at the Westfalenstadion.
His £58m switch to Arsenal eclipsed the £52m transfer fee that the Gunners spent on his strike partner Lacazette, who arrived from Lyon in the 2017 summer transfer window.
