He has now scored seven goals from Gameweek 8 onwards, joint-top with Sadio Mane (£12.4m) in midfield.
Grealish tops the FPL form table among midfielders, having averaged 6.5 points per match over the last 30 days.
They rank second and third respectively for points-per-million value among midfielders this term.
Traore’s team-mate Raul Jimenez (£7.5m) ended a run of three matches without an attacking return with two goals at St Mary’s Stadium.
Over a third of the Argentinian's FPL points this season have come in his last three appearances for Pep Guardiola's side.
Aguero is already the most-bought player in the Gameweek, earning more than 42,000 new owners ahead of a trip to Sheff Utd on Tuesday evening.
Paulo Gazzaniga (£4.6m) also impressed in the goalless draw at Vicarage Road.
He saved Troy Deeney’s (£6.2m) penalty to deliver 14 points, currently the highest points total in the Gameweek.
Elsewhere, Federico Fernandez (£4.4m) continued his strong home form with nine points in Newcastle United’s 1-0 win over Chelsea. The centre-back has averaged 4.8 points per start at St James’ Park this season.
Chelsea’s Reece James (£5.0m) also profited in Saturday evening’s encounter as he was withdrawn late in the second half while the score was goalless.
James therefore kept his clean sheet and also picked up two bonus, taking his total to 19 points in two Gameweeks.
However, he sustained a knock against the Magpies and is now rated doubtful for the Blues' Gameweek 24 home encounter with Arsenal on Tuesday.
