Tottenham captain Hugo Lloris for barracking Davinson Sanchez during defeat to Bournemouth.
A first-half substitute, Sanchez was eventually replaced in the second-half after several errors.
"It started earlier, it's when he came on the pitch," captain Lloris told beIN Sports.
"I've never seen this in my career. I feel really bad for Davinson. He's a team-mate, he's a friend and he's been fighting for the club for many many years now, and it's just sad.
"The story is sad for the club, for the fans, for the player. It's something you don't want to see in football."
