Bakayoko scored his first goal for Chelsea in their Champions League rout of Qarabag last night.
“I know him from playing against him in the past, I knew some of his friends from before so that’s why we have a great relationship,” Luiz said.
“We speak French together. It’s also good for me to keep learning and practising French!
“He’s a great guy, a great person, great player.
“He’s a fantastic talent and for sure he’s going to give a lot of happiness to all the supporters of Chelsea.”
