Vinícius only returned to Madrid on Thursday after starting Brazil’s draws with Venezuela and Uruguay during the international break.

“Mbappé was fresher than Vinícius,” Ancelotti admitted after Sunday’s game. “He scored the goal very well after a fantastic assist from Vini. Little by little they both get better.”

Vinícius, who swapped positions with Kylian Mbappé in Madrid’s attack on Sunday, will miss several games, including Wednesday’s clash at Liverpool.

Madrid go into Wednesday’s game at Anfield needing a win, having lost twice in four Champions League games so far.

Mbappé, who was assisted by Vinícius for Madrid’s first goal on Sunday, spoke of his growing partnership with the Brazilian striker.

“Vini Jr. and I got along very well,” he said.

“I have a great relationship with him and he is a great player. The best players are here and we are ready to win a lot of games and trophies.”

Vinícius has scored 12 goals and assisted eight more in 18 league games for Madrid this season.
