Fabinho played for Real Madrid earlier in his career.
Marca reports Florentino had come down to see the Real Madrid players after the 3-1 victory, while Vinicius Junior had just finished his TV commitments after being named man of the match. Upon seeing Fabinho, the Real Madrid president discussed the Brazilian's days playing for Castilla in the 2012/13 campaign.
"With us you played as a right-back," Florentino recalled to Fabinho.
"Yes, but to play right-back now... What a player you have in Vinicius," the Liverpool player responded.
Vinicius scored two goals in the victory and his impressive performance was recognised by Fabinho.
