Cole has been impressive since joining Lille on-loan in August.
As he reflected on his great start across the Channel, he said: "A big difference is the underwear players have. Here, they wear crazy stuff... prints, colours.
"If you wear that in England, other players burn it or throw it way. But this is France and fashion.
"Pink, orange, green, fluorescent... and they play wearing that too. They have a sense of humour."
