Inter Milan's Marcus Thuram can usually count on his father Lilian's support whenever he plays but Sunday's Serie A match against Juventus will be a different story with his brother Khephren set to line up on the other side of the pitch.
Former France defender Lilian spent five years at Juventus, winning two Serie A titles, before ending his professional career at Barcelona.
"It will be a beautiful match, the whole family will be at the San Siro," Marcus, 27, told Sky Sport Italia. "My dad will definitely support Juventus, he played there."
Forward Marcus came off the bench and scored in added time to help Inter win 1-0 at Young Boys in the Champions League on Wednesday.
Juventus defensive midfielder Khephren, who joined from Nice in July, said the brothers were happy and proud to play against each other.
"Now we're two professional players. We dreamed of that as kids," the 23-year-old said earlier in the week. "We have to do our best to play a very good game."
Inter are two points behind leaders Napoli with 17 points from eight matchers. Juventus are third a point further back.
