'Vinicius is victim': Ancelotti blasts La Liga's 'problem' with racism
"The Spanish league has a problem, and Vinicius is not the problem. Vinicius is the victim. There's a very serious problem," Ancelotti said, adding that Vinicius was "sad, not angry" after the incidents at Mestalla.
Midway through the second half play was delayed for several minutes after Vinicius appeared to be racially abused by a Valencia supporter.
The Brazilian forward stood in front of the fans behind the goal and pointed to one, with team-mate Eder Militao by his side.
Vinicius was later sent off in added time at the end of the game for hitting Hugo Duro during a brawl, with Valencia triumphing through Diego Lopez's first-half goal.
"The fact I thought about taking him off because of the racist atmosphere does not seem good to me," Ancelotti told reporters.
"What has happened today has happened before, but not like that, it's unacceptable."
Vinicius has been racially abused at several stadiums this season in Spain and an effigy of him was hung from a bridge in the Spanish capital by Atletico Madrid fans.
La Liga have filed legal complaints to Spanish authorities on multiple occasions this season, with the league pledging on Sunday to do so again after investigating.
However Ancelotti said it was not helping.
"What has happened? Reports, and nothing at all has come from it. The solution is to stop the game," continued the coach.
"I am very sad, this has never happened to me -- I've never had to take off a player because of insults.
"He's a kid, he likes playing football, but in these conditions it's very complicated."
Vinicius took to Instagram after the defeat.
"The prize for the racists today is that they have sent me off. It's not football, it's La Liga," wrote the 22-year-old.
The attacker said Spain was viewed as "a country of racists" in his homeland Brazil.
"The league that once belonged to Ronaldinho, Ronaldo, Cristiano (Ronaldo) and (Leo) Messi, now belongs to racists," added Vinicius.
After Vinicius' stand-off with Valencia supporters, referee Ricardo de Burgos Bengoetxea spoke to stadium officials, who made an announcement calling for racist insults to stop before play resumed around 10 minutes later.
"There's a lack of respect for Vinicius shown continuously at almost every stadium in Spain," Madrid midfielder Dani Ceballos told Movistar.
"It's true the coach asked him if he wanted to keep playing.
"Vinicius is a professional and said he wanted to keep helping the team, but we see that we can't do anything."
Madrid goalkeeper Thibaut Courtois said he heard some "monkey noises" after around 20 minutes and said he would have walked off with Vinicius if the Brazilian chose to stop playing.
"If Vini wants to keep playing, we keep playing, but if Vini says he's not playing any more, I'm leaving the pitch with him, because we cannot tolerate these things," Courtois told Movistar.
Football forgotten
Players from both sides ended up in a brawl in stoppage time which ended with a red card for Vinicius for lashing out at Duro with his arm, although the Valencia forward was pictured with his arm around the Brazilian's neck.
Vinicius left the pitch making a gesture with his hands indicating Valencia were heading down to Spain's second division.
Valencia had taken the lead in the 33rd minute when Lopez escaped Ferland Mendy and tucked home at the back post.
Valencia rose to 15th with the win, five points clear of the relegation zone, sparking huge celebrations at full-time, with the team almost safe.
