The Gabon international moved to Arsenal in a £56m deal from Bundesliga giants Borussia Dortmund in the January transfer window in 2018.
Aubameyang became the club’s most expensive signing following his move to the Premier League club following Alexis Sanchez’s switch to Manchester United.
The 28-year-old scored on his Arsenal debut in a 5-1 win against Everton at The Emirates at the start of February before the striker failed to find the net in successive games against Manchester City and Tottenham Hotspur.
The African forward has scored in his last two Premier League games following goals against Brighton and Hove Albion and Watford.
Aubameyang will be sidelined for their home clash against Serie A giants AC Milan in the second leg of their Europa League last-16 fixture at the Emirates Stadium on Thursday night.
Mustafi believes the Gabon forward still needs more time to settle at Arsenal following his record move to the north London club.
“Obviously they’ve known each other for a long time, but football isn’t about one pair, or three players playing together,” Mustafi told Arsenal’s website.
“We need to find more solutions as a team playing from the back up to the front and through the whole team.
“We have to try to find more solutions so we can bring everyone’s strength [into play]. That’s when we are at our best, when we can play the way that everyone is playing at their strengths. Then we achieve different results.
“For Pierre, I think it’s a little bit too early to make a statement, because I think it needs time. He needs games to see how he’s going to settle.”
Arsenal finished in fifth place in the Premier League table and a point behind Liverpool FC to miss out on a place in the Champions League for the first time under Arsene Wenger.
