The Scout is selecting three overlooked players who could be set for a breakout Gameweek 6 in Fantasy Premier League.
Mendy made his return from long-term injury in Wednesday's UEFA Champions League match against Shakhtar Donetsk, featuring as a late substitute in a 3-0 win.
He will now be pushing for a start against the Hornets this Saturday.
And his output from last season highlights his all-round potential in Fantasy.
Despite being limited to 10 appearances, Mendy supplied six assists in 2018/19, in addition to four clean sheets.
To put this into perspective, only seven other FPL defenders bettered Mendy's assist haul throughout the season.
By comparison his rival for the left-back role, Oleksandr Zinchenko (5.6m), managed three assists in 14 appearances.
Having played only one league match since last November, Mendy may well be rotated with Zinchenko until he regains full match fitness.
But if the Frenchman is unleashed from the start against Watford, he can reward those who are willing to accept that risk.
