The Gabon international moved to Arsenal in a £56m deal from Bundesliga outfit Borussia Dortmund in the January transfer window.
The 28-year-old arrived at the Emirates Stadium with a big reputation following an impressive return of 141 goals in 213 appearances during his four and a half season stay at the Westfalenstadion.
Aubameyang scored on his Arsenal debut in a 5-1 win against Everton in February, while he has found the net in successive games Brighton and Hove Albion, West Brom and Stoke City.
The African forward scored twice in last weekend’s 3-0 win over Stoke before he handed the ball to Alexandre Lacazette to net from the spot despite winning the penalty and being on a hat-trick.
Former Arsenal defender Keown believes Aubameyang has proven his critics wrong with his positive attitude at the north London side following his deadline day move.
“He has that killer instinct you need to be a top striker, but he smiles when he scores,” Keown told the Daily Mail.
“He has this joyful exuberance that looks to spread throughout the team. Whenever Alexis Sanchez scored, you weren’t sure he was truly happy, and that mood can infect a team. People were saying Aubameyang’s arrival would harm the dressing room, but he’s provided a lift.”
Arsenal finished in fifth place in the Premier League table last season to miss out on a Champions League spot for the first time under Arsene Wenger.
The Gunners were 4-1 winners against CSKA Moscow in the Europa League quarter-final at The Emirates on Thursday night.
