The Scout is selecting four overlooked players who could be set for a breakout Gameweek 7 in Fantasy Premier League.
Walcott played for just 12 minutes as a substitute in the opening four Gameweeks while at Everton.
But his loan move to Saints can revive his prospects in FPL.
Walcott was immediately handed a start for Southampton's visit to Chelsea in Gameweek 5.
He played the full 90 minutes at Stamford Bridge and supplied the assist when Jannik Vestergaard (£4.5m) scored the late equaliser in the 3-3 draw.
The 31-year-old was unavailable for the 2-0 win over the Toffees in Gameweek 6 due to the conditions of his loan deal.
Nonetheless, Walcott's numbers from Gameweek 5 suggest he will make an immediate return to the starting XI at Villa Park.
He was a key outlet for the match at Chelsea, creating five of Saints' eight chances.
Walcott now faces a Villa side who have struggled in defence in recent home matches, conceding five goals in their last two.
That suggests Saints' summer signing can build on his display against Chelsea and provide a cut-price source of points in Gameweek 7.
