Speaking to The Telegraph, Palmer said, "I first did the ‘cold’ celebration last December in a game against Luton where we won 3-2. It’s a nod to my former City academy team-mate Morgan Rogers [who is now at Aston Villa].
"It symbolises joy, passion and hard determination for the game plus it’s funny as it works well with my name. Everyone knows it’s my celebration. Lots of people might have done it, but everybody knows it is my celebration."
