Aubameyang found the net on his debut in a 5-1 thumping of Everton but the Gabon worldwide believes not being eligible for the Europa League has hampered his progress.
The win keeps Wenger's side sixth in the Premier League, however, it will give them some added confidence for their clash with the Serie A outfit on Thursday as they look to progress in Europe.
Ahead of their crucial second-leg fixture against AC Milan in the Europa League on Thursday, Arsenal have been handed a massive injury boost.
Ainsley Maitland-Niles conceded a penalty with a foul on Pereyra, but when Deeney stepped up to take the spot-kick, Cech made a fine save. I wanted to preserve some players, like Koscielny, who has a little calf problem. I remember very well every time he refused the biggest clubs to stay at Arsenal. "We took only 18 games to get nine clean sheets at the start of the season to reach the 199 and we had to wait 11 games, which is sometimes frustrating".
Cech more than played his part, saving a second-half penalty from Troy Deeney to help the Gunners secure a much-needed 3-0 victory. "Fantastic motivation, fantastic desire and remarkable intelligence", he said.
Ray Parlour still doesn't expect Arsene Wenger to be at Arsenal next season.
The under-fire manager's first victory came against Blackburn Rovers way back in 1996, when Ian Wright scored twice in a 2-0 win at Ewood Park. "We feel the confidence is back", Aubameyang said. That kept us out of trouble.
The Gabon international's goal put Arsenal 2-0 up as he pounced on a pass from former Borussia Dortmund team-mate Henrikh Mkhitaryan to score. I didn't play a lot in January so it was hard to find a rhythm.
