The three finished tied on 22 goals at the end of the season with both Aubameyang and Mane netting twice on the final day
The Gabon international netted twice on the final day of the season to end with 22 goals in his first full season with the Gunners.
Senegal star Sadio Mane also scored twice on the final day to end on 22 while Egypt forward Mohamed Salah, and Liverpool team-mate, was at the top of the list as well.
Aubameyang told The Sun: “It means a lot. I am really happy and proud of it.
“I am sharing this trophy with Mane and Salah – and I like these two guys. We are representing Africa so it is a good sign for the Continent. I am really proud and I have to thank my team-mates for helping me to get it.”
The 29-year-old has 32 Premier League goals in 49 games for Arsenal since joining in January 2018 and he has vowed to get better in the toughest league in the world.
He said: “Now you can say the Premier League is the best in the world because four clubs are in the finals and as we saw this season, Liverpool and Manchester City played the last game for the title. So that’s why I came here, for that.
“It is always a tough battle when you play a game here in England and you have to be ready physically. That’s the most important change when I came here from Germany.
“It took a little bit of time. I had six months to adjust me to this league. I think I did well in the first six months and now I have the whole season. I am happy with that. Hopefully I will do better next seasons.”
Aubameyang still feels disappointment at missing out on the top four and is targeting Europa League glory in a fortnight for a successful campaign.
He said: “I had great seasons as well in Dortmund. This one was a tough one. I would say in truth maybe not the best but I gave everything to try to be in the top four with the team and to get a trophy.
“I am happy with my season, not the best but I am happy.”
