Paris-Saint Germain centre-back Marquinhos broke down in tears at the thought of Lucas Moura leaving the club in January.
The Brazilian failed to hold back his emotions when discussing the future of his compatriot, claiming he just wants him to be happy.
In an interview with Canal +, the 23-year-old cried at the thought of the distance between the two should he depart Parc des Princes.
He said: "It's sad when we see a friend like that.
"It's a friend who has done me a lot of good here in Paris since my arrival. I would not want to be in his situation because a player needs to play.
"It's to have foot on the ground and I think he'll make his choices and we'll be with him. That's why I'm like crying to imagine him leaving."
Speaking on the Olympic silver medallists happiness, Marquinhos added: "I will not think of being selfish to want him here with us every day. I wish he was happy, a friend should wish and I wish him.
"It is a friend that I will save for life. Even from afar I will wish him the best.

Lucas signed for Les Parisiens in 2012, and has racked up close to 250 games in all competitions, netting 45 times in a hugely successful period for the club.
