Sherwood was sacked by the Foxes' Midland rivals earlier this season and both clubs have experience polar opposite campaigns.
While Villa have been rooted to the foot of the league and look absolute certainties for relegation, Leicester have set the Premier League alight and are three points clear at the top with just 15 games remaining.
But as the likes of Jamie Vardy and Riyad Mahrez get much of the credit for the amazing season Claudio Ranieri's men are enjoying, Sherwood preferred to highlight the work of one of their more unsung heroes.
'He's like a bad rash'
"He is a huge find," Sherwood told MOTD.
"Don't forget they are playing a 4-4-2 so him and (midfield partner Danny) Drinkwater are covering a lot of distance.
"This is one player I would have hated to play against, he's all over you like a bad rash you just cannot shake him off.
"He's got everything, you leave him a bit of space he opens up passes off his left side, his right side. When there is space to drive, he drives the team forward and they're a very good counter attacking team because of this fella.
"If there's any fires he puts it out.
"I know it's not his position but if he added goals, he'd be at Real Madrid next year."
Bargain of the season
Whether the midfielder could cut it at Madrid is one thing, but he certainly deserves his share of the plaudits for Leicester City's stunning season.
Kante was spotted playing for French side Caen by the club's head of recruitment Steve Walsh, as reported by the Telegraph.
And at £5.6 million what a signing he has turned out to be.
The 24 year-old has a lung busting ability to get about the pitch, close down opponents and seemingly cover every blade of grass.
If Leicester do the unthinkable and qualify for the Champions League or go one better and win the title, he will have been the beating heart powering it.
