The former Villa boss was left enraged on social media!
The former Aston Villa boss didn't so much take issue with Leicester themselves - or their fans - but rather the situation Villa find themselves in.
Indeed, as the Foxes took on Chelsea and let Jamie Vardy and Riyad Mahrez showcase their quality yet again in this enthralling Premier League season, the home fans chanted to their London counterparts: 'You're going down with the Villa.'
And Gregory took to Twitter angered by the chants and embarrassed by the fact they were being sung in the first place.
#AVFC King Power Stadium tonight...I have never in all my days had to endure the embarrassing chant of "You're going down with Villa !!!"— John Gregory (@JohnGregory77) December 14, 2015
The contrast between Leicester and Aston Villa couldn't be starker right now and that's demonstrated by the Premier League table.
Claudio Ranieri's men sit top of it. Villa sit bottom.
Next up for Aston Villa is a trip to Newcastle United, while Leicester will look to continue their fine form against Everton at Goodison Park.
What a season it's turning out to be for the Foxes; it's getting to a stage where, even if they dramatically collapse, they will already have enough points in the bank to enjoy a strong end-of-season position!
