Arsene Wenger signed Lacazette in a club record £52m deal from Ligue 1 side Lyon in the 2017 summer transfer window.
The France international found his first-team spot under threat following the signing of Aubameyang from Borussia Dortmund in January.
Indeed, the Gunners smashed their club record fee with the £58m signing of the Gabon international from the Bundesliga outfit.
Aubameyang has scored 10 goals in 14 games in all competitions, while Lacazette has netted 19 times in 45 outings since his move to Arsenal last summer.
However, Aubameyang and Lacazette appear to forming a devastating strike partnership after the duo got on the score sheet in Arsenal’s 2-0 win over Everton.
Former Arsenal playmaker Nicholas believes Lacazette has a vital role to play in the Arsenal team under Emery.
Nicholas told Sky Sports: “Aubameyang is better than Lacazette, but Lacazette is really good because he likes to get on the shoulder of people.
“If anybody notices with Arsenal, Lacazette’s touch and spin and link-up with Aubameyang – I think Cardiff is where they showed it best – they have that, this partnership and togetherness, and the feeling between the two of them.”
Arsenal are in sixth spot in the Premier League table and a point adrift of Watford, who occupy the final Champions League spot.
The Gunners will welcome Watford to the Emirates Stadium in their next Premier League game on Saturday.
The north London side finished in sixth place last season to miss out on a Champions League spot for the second successive campaign.
