Willian has already been brought in by over 40,000 managers ahead of next week's Gameweek 25 deadline, second only to Sergio Aguero (£11.8m and 47,000+).
The Brazilian's display at the Amex Stadium marked the third occasion in his last five starts that he has produced both a goal and an assist in a single match.
Indeed, the comparison with team-mate Eden Hazard (£10.6m) since Gameweek 16 is significant.
Willian has supplied three goals and five assists at a rate of 6.1 points per match and 9.1 minutes per point over that nine-match period.
By contrast, Hazard has contributed only three goals and an assist, making one fewer appearance but playing more minutes (621 v 503) overall.
The Belgian has supplied 5.5 points per match, at a rate of 14.1 minutes per point, lagging behind Willian on both counts.
The underlying statistics support these results.
Hazard's ICT Threat score from Gameweek 16 is superior (363 v 288.5) but Willian has been more accurate with his shooting, firing 10 shots on target to his team-mate's nine.
And Willian wins out for ICT Creativity (347.3 v 261.5) having supplied 24 chances to Hazard's 19, in 118 fewer minutes.

Despite his recent form, however, the midfielder's starting role in Antonio Conte's line-up is not assured.
He last made four successive Premier League starts back in Gameweeks 5-8 and was withdrawn before 72 minutes in each of those four outings.
And with Pedro (£7.7m) back from his one-match suspension and the UEFA Champions League tie with Barcelona looming, FPL managers should be wary of rotation.
