Aubameyang netted an important penalty for Arsenal in the 2-0 win over Manchester United on Sunday in the Premier League after Lacazette was brought down in the box by Fred.
The Gabon international stepped up to dispatch his spot-kick to wrap up the three points for the north London side after having missed a penalty in the 1-1 draw with Tottenham the week before.
And Aubameyang has opened up about how his on-pitch understanding with Lacazette has helped to give him confidence in recent games.
Speaking in an interview quoted by Metro, Aubameyang said: “This friendship is really really strong.
“Straight after he fell down, he looked for me and said: ‘You shoot. You have to be focused and you shoot’.
“It’s a great partnership and, of course, the coach decides who plays and whether we play together or not.
“And we have to accept that, that’s normal. But I think we are both really focused on playing for the team and giving our best.
“We don’t care about who is shooting the penalty, the most important thing is to score.
“After Laca got the penalty and looked at me, I felt good and I was ready to score because we are having a good period with the team and everybody said that I would score again.
“I watched the penalty I missed a lot. I knew that I made a mistake when I shot last week. But in life you have to always look forward and I had to be focused. That’s what I was against United.”
The 29-year-old Aubameyang has been in solid form for Arsenal so far this season, scoring 17 goals and making four assists for Unai Emery’s men in 29 Premier League games.
Arsenal will return to Europa League action on Thursday night when they host Rennes in the last 16 of the Europa League looking to overturn a 3-1 deficit from the first leg.
The Gunners are not in Premier League action again until Monday 1 April, when they will host Newcastle United in the top flight at The Emirates.
Arsenal are fourth in the table as they look to try and seal a top-four finish this season for the first time in two years.
