The Arsenal star also earned two bonus points in Monday's 3-0 win, bringing in 15 points.
Aubameyang has now produced both of his double-figure returns this season in his last five Gameweek appearances.
But despite his improving form, the Gabonese’s price tag remains a big deterrent in Fantasy.
His midfield team-mates Bukayo Saka (£5.3m) and Emile Smith Rowe (£4.5m), who combined for the second goal, continue to offer far greater value.
Saka’s strike took his tally to three goals, two assists and 39 points in the Gunners’ last five Gameweeks.
Smith Rowe has started each of those last five matches, supplying four assists in that period.
The 3-0 win also extended Arsenal’s fine run of defensive displays.
Mikel Arteta’s side have now kept a clean sheet in four successive Gameweeks.
By comparison, they had managed just three shutouts in their opening 15 encounters.
Cedric Soares (£4.6m) had a major impact in his first start of the season against Newcastle.
The right-back provided an assist and also collected the maximum three bonus points to total 12 points.
Meanwhile, the clean sheet took Arsenal No 1 Bernd Leno (£5.0m) to 79 points for the season, just four points off the top of the goalkeeper standings in Fantasy.
