Having made only a single player swap up until Gameweek 19, he opted for the Wildcard chip to boost his squad.
However, Barry then embarked on a further hiatus, making only his second and third transfers of the season ahead of last weekend.
But both deals proved masterstrokes that capped an unbeatable 121-point Gameweek 25 tally.
The move for Burnley's Robbie Brady (£5.5m) was perhaps more impressive.
Owned by only 2,766 FPL managers, his Irish compatriot provided Barry with immediate rewards courtesy of a home-debut goal against Chelsea in Sunday's 1-1 draw.
The contributions of these two Gameweek signings were key factors, although it was the impact of captain Alexis Sanchez (£11.8m) that was to power Barry's triumph.
With the Triple Captain chip deployed, Arsenal's Chilean (a mainstay in Barry's squad since Gameweek 1), provided a 45-point haul from a 2-0 victory over Hull City.
Sadio Mane's (£9.2m) brace and 16 points in Liverpool’s win over Tottenham Hotspur provided able support to Sanchez, before Barry sealed his Gameweek victory on Monday night as Manchester City's Raheem Sterling (£7.8m) and Sergio Aguero (£12.7m) combined to return another 15 points.
In his fourth FPL campaign, his unrivalled triple-figure tally helped Barry climb almost a million places in the overall rankings.
As Manager of the Week, Barry wins a copy of FIFA 17, a Nike Ordem 4 match ball and an FPL mug, all packaged in a Fantasy Premier League rucksack.
