"It does make me very proud," Mancienne said of welcoming his former club to New England, especially for such an important reason.
"It's a special moment, especially because of what the game stands for. As athletes, we have a platform to stand up against discrimination and show the world we don't stand for these kind of hateful things. To do it like this is brilliant. Obviously, to play against one of the best teams in the world is fantastic too, and to play against the club I grew up with and came through the Academy with is massive. It's really exciting and I'm looking forward to it."
Mancienne was named Chelsea's Young Player of the Year before he left.
"Yeah, I did, they're fantastic memories. It was obviously a great honor to be the Young Player of the Year at Chelsea and to get that medal. They're just great memories, being there at the time, the team felt like it was a family. I loved going into training, I loved being around the world-class players. I really looked forward to training every day and making myself a better player."
