However, does the win do enough to justify why the Frenchman should stay at King Power for next season?
The Foxes ended a miserable run of five games without a win and six at the King Power Stadium by inflicting a first-ever defeat to the Gunners.
The victory, courtesy of goals from Kelechi Iheanacho, Jamie Vardy and Riyad Mahrez, ensured Puel’s side now cannot finish lower than ninth.
After the win, Puel dedicated the final home game of the season to his Leicester supporters, despite many fans wanting a change of management in the East Midlands.
Puel took over from Leicester with the Foxes sitting third from the bottom – a position that had resulted in the sacking of Craig Shakespeare back in October.
Puel was a breath of fresh air for the former Premier League champions and got them quickly flying up the league table.
However, his poor form in recent weeks has also seen fans unhappy with his unimaginative style of play, and some have called for their fourth managerial change in just over a year.
The current Leicester boss found himself in an almost identical position last season when he was sacked by Southampton on the final day of the season, despite guiding the team to an impressive 8th place finish.
It comes as a cruel reminder to Puel that wins just aren’t enough in the modern game. Fans still want to see their team playing a positive brand of football that lifts them off their seats each weekend.
Puel’s obsession with results had clearly upset the Leicester dressing room, who looked jaded and unimpressed with the manager’s tactics in recent weeks, but Wednesday’s win may inspire the board to keep the 56-year-old in charge of the Foxes for next season.
Leicester can’t afford to keep going through managers and Puel’s style may not be the most imaginative, but the former Saints manager has dragged them up the table dramatically when they looked a serious contender for the drop just months ago.
The supporters need only look to Burnley for inspiration, with the Clarets recording a stunning seventh place finish that has secured them European football for next season.
Puel has an 8th and 9th place finish on his managerial CV, and supporters should be delighted with the progress made since his appointment back in October.
