The France international has given the north London side a commanding lead in the Europa League quarter-final tie thanks to his two goals in a 4-1 victory over CSKA Moscow in the first leg.
Lacazette and Aaron Ramsey both scored twice to secure a first-leg lead ahead of their long trip to Moscow with a place in the Champions League the prize for the competition’s winner.
The 26-year-old has scored 10 times in 28 appearances in the Premier League this season following his £52m move to Arsenal from Ligue 1 side Lyon in the 2017 summer transfer window.
Arsenal are in sixth place in the Premier League table and 13 points adrift of Liverpool FC and Tottenham Hotspur, who occupy the final two top-four spots.
As a result, the Europa League represents Arsenal’s best chance of securing a return to the Champions League after missing out in the 2017-18 season.
Former Chelsea FC midfielder Lampard highlighted why Lacazette is key for Arsenal against CSKA Moscow on Thursday night.
“Arsenal will need him [Lacazette] if they get past CSKA Moscow as expected on Thursday and then play teams like Atletico Madrid or Lazio in the last four,” Lampard told the Evening Standard.
“Strikers make the difference in these kind of games. There is even more scrutiny on him.
“If he can show he can react, then there’s nothing wrong with Arsenal having two top strikers in the squad, whether they play together or are rotated.”
Arsenal were 3-2 winners against Southampton in the Premier League on Sunday thanks to Danny Welbeck’s winner.
