Crooks was impressed with the performance of the Algeria international against West Bromwich Albion away from home in the Premier League on Saturday.
The 24-year-old scored twice, took four shots, had a pass accuracy of 69%, created one chance, put in six crosses, attempted three dribbles, and made one interception, two clearances and one block.
Former Tottenham forward Crooks has included Mahrez in his BBC Premier League Team of the Week and wrote on BBC Sport: “I suppose if you are going to be ghosting in from either side of the pitch to score two brilliantly taken goals you might as well do it on Halloween weekend.
“Mahrez was reminiscent of former West Ham, Spurs and Norwich player Martin Peters at his best the way he floated in on West Brom's blind side.”
Crooks has also included Leicester striker Jamie Vardy in his BBC Premier League Team of the Week due to the England international’s performance and goal in the 3-2 at West Brom.
“There are very few centre forwards who can make their own goals but Vardy can,” Crooks wrote on BBC Sport. “His blistering pace allows him to get away from defenders if the set-up play is right.
“Such was the case against West Brom when the England striker ripped the heart out of the Baggies with an emphatic finish.”
Leicester are third in the Premier League table at the moment with 22 points from 11 matches, just three points behind leaders Manchester City.
