Fielding a five-man defence proved to be an inspired move by Brunei manager Radin Udara.
His Admin kotw team brought in 122 points to earn him Gameweek 7's Manager of the Week accolade.
A goal, assist, clean sheet and maximum bonus points helped Maguire to a second double-digit haul of the campaign as the Foxes beat Newcastle United 2-0.
Three other members of the Dream Team defence could also be found in Radin's side.
Wolverhampton Wanderers duo Jonny (£4.4m) and Matt Doherty (£4.5m) brought in 12 points each, while Tottenham Hotspur wing-back Kieran Trippier (£6.2m) recorded 11 in the 2-0 win at Huddersfield Town.
The winger's fourth goal of the season, and his second assist, produced 14 points as Pep Guardiola's side saw off Brighton & Hove Albion 2-0.
As the manager with the highest score among those not using any of their chips, the Cardiff City fan wins a copy of FIFA 19, a Nike Merlin match ball and an FPL rucksack and mug.
