The centre-back also recorded a clean sheet and earned the maximum three bonus points in Burnley's 3-0 win at Vicarage Road.
Tarkowski’s 17-point return is currently the highest of the Gameweek. He was also the joint-top scorer in Gameweek 12 with 12 points.
Leicester striker Jamie Vardy (£9.7m) was the most-selected captain in Gameweek 13 and he enjoyed yet more success.
Vardy banked his fifth double-digit haul of 2019/20 with a goal, an assist and maximum bonus at the Amex Stadium, becoming the first player to pass 100 FPL points this term.
And Saints striker Danny Ings (£6.0m) extended his run of goals with the opener at Emirates Stadium.
Ings has scored in five of the last seven Gameweeks, and his schedule further strengthens his appeal as a cut-price forward.
Four of Southampton's next five matches score just two in the Fixture Difficulty Ratings (FDR).
Son Heung-min (£9.7m) was Spurs’ top performer, with a goal and an assist earning him 13 points.
He is currently the most-bought FPL player for Gameweek 14, earning 88,000+ new owners.
The Canaries also had Tim Krul (£4.5m) to thank at the other end of the pitch at Goodison Park, with the Dutchman’s seven saves earning him 11 points against the Toffees.
Owned by just 1.6 per cent, Krul remains a strong differential thanks to his save-point potential. Norwich’s No 1 has produced 36 points in the last five Gameweeks since returning from injury.
