A 25-year-old midfield lynchpin, Gardner arrived at Oakwell on a season-long loan from Championship rivals Aston Villa.
A former England U21 international, Gary has played over 100 games at the level and spent successful spells out on loan, most recently with Nottingham Forest.
Falling down the pecking order at Villa Park owing to the influx of new signings since their relegation from the Premier League, the midfield man chose the Reds as his destination despite many suitors on Summer Deadline Day 2017.
After an injury on debut that ruled him out for 8 weeks, 'Gards' soon forced his way into the XI and steadily found his feet in the Reds midfield, scoring vital goals, particularly a scorcher against rivals Sheffield United in a 3-2 win.
