Jurgen Klopp’s side and the Gunners have both won their two opening Premier League games ahead of their match at Anfield on Saturday evening.
Aubameyang has scored in both matches, while Lacazette opened the scoring in the 2-1 victory over Burnley last weekend.
Pepe, meanwhile, is yet to be handed his first start since his £72 million move to Arsenal in the summer.
But Wright feels the match against Liverpool is the right time to deploy Pepe from the start in order to exploit the gaps left by Trent Alexander-Arnold and Andy Robertson..
‘I think Arsenal now should know that Liverpool, they came out fast,’ Wright said on The Kelly & Wrighty show.
‘They come out fast, for some reason against Arsenal they come out even faster. Arsenal have got to be ready for that.
‘I think that the midfield, in respect of our midfield now, there’s players in there that I feel are more comfortable on the ball.
‘This is why it’s vitally important that Pepe starts and Aubameyang and Lacazette because if we can then win the ball from Liverpool, who are finding their feet, we might be able to get into the spaces that Trent Alexander-Arnold may leave, what [Andy] Robertson might leave.
‘Then all of a sudden you’re giving Liverpool a whole different problem, especially if they’re playing as high as they’ve been playing recently.’
