The Frenchman netted twice in a 4-0 win over West Bromwich Albion on Saturday.
He has scored four of his seven goals this season in the last three Gameweeks, claiming 27 points in that period.
Arsenal are one of only 12 clubs with a Premier League fixture in Gameweek 18, which raises the appeal of Lacazette as FPL managers look to navigate the restricted schedule.
There is value to be found elsewhere among Mikel Arteta's in-form side.
Bukayo Saka (£5.2m) has two goals and two assists in the last three Gameweeks.
And since making his first start of 2020/21 in Gameweek 15, budget FPL midfielder Emile Smith-Rowe (£4.4m) has delivered three assists in as many matches.
The Gunners' defensive assets have also impressed, with Kieran Tierney (£5.3m) the main draw on the back of his 18-point haul at The Hawthorns.
But centre-halves Rob Holding (£4.5m) and Pablo Mari (£4.4m) offer cheaper routes into a rearguard that have recorded consecutive clean sheets.
Son and Kane shine again
Son Heung-min (£9.7m) recorded his seventh double-digit haul of the campaign in the 3-0 win over Leeds United, moving back to the top of the FPL player standings.
And a goal and assist for Harry Kane (£11.0m) means the England striker now has 21 attacking returns this season, one more than he managed in the whole of 2019/20.
The story of Son's 100 Spurs goals
At the other end of the price scale, one of FPL's cheapest defenders started his second successive match after regaining his place in Palace's starting XI.
Tyrick Mitchell (£3.9m), who is still the fifth most-owned player in his Fantasy position, helped the Eagles to a 2-0 win over Sheffield United.
Neto a bargain
Wolves attacker Pedro Neto (£6.0m) registered his ninth attacking return of the campaign with an assist in the 3-3 draw.
No outfield player priced at £6.0m or under can better Neto's total of 80 points this season.
Brighton's Leandro Trossard (£5.7m) also impressed, supplying two assists to record his season-high haul of 11 points.
