Mahrez picked up PFA Player of the Year en route to inspiring Leicester City to a fairytale title last term.
The decisive moment came at Stamford Bridge when Tottenham spurned a two-goal half-time lead in dropped points which confirmed Leicester as champions.
Mahrez and his team-mates were watching the match at Jamie Vardy's home, and the Foxes' wild post-match celebrations went viral on the internet shortly after.
And the Algerian star admits that he had no room to sympathise with Spurs, commenting that their capitulation was "funny" under the circumstances.
"The funniest moment? I think it was when Tottenham were 2-0 ahead of Chelsea. All the team were at Vardy's house thinking 'we're probably not going to be champions tonight'," he told Four Four Two.
"I was like, 'What's the point of coming?!' and then 2-1, 2-2... it was funny."
Mauricio Pochettino's side managed to finish 11 points behind Leicester in the end, and their capitulation got worse as Arsenal pipped them to second spot on the final day of the Premier League season.
At the moment, it seems unlikely that the Lilywhites will right the wrongs of last season as their 2-1 defeat at Chelsea this past weekend saw them fall seven points behind the Blues, who lead the way in the Premier League table.
