Carlo Ancelotti hit out at Javier Tebas on Friday, saying the LaLiga president is "obsessed" with Real Madrid and "lacked respect" for coaches after Tebas' latest comments in the row over players' rest between games.
Ancelotti has said his team will refuse to play in future if they are given fewer than 72 hours' break, after Madrid were unhappy with LaLiga's scheduling of their 2-1 win at Villarreal on March 15.
Tebas appeared to indirectly criticise Ancelotti's management of his players when asked about the issue at a conference on Thursday, saying "since COVID, you can make five substitutions, but then you make three substitutions in the 85th minute, and you complain."
"I knew [Tebas] was obsessed with Real Madrid, but I didn't know he wanted to be a coach," Ancelotti responded, when asked about the comments in a news conference on Friday. "[Tebas] should focus more on his own things. He lacked a bit of respect, to Real Madrid and to coaches."
The scheduling row is the latest in a series of clashes between Madrid and the league on a number of issues.
Speaking ahead of Madrid's game with Leganés at the Santiago Bernabéu, Ancelotti sought to add some nuance to his threat.
"I must add something: we won't play [with under 72 hours' rest] without justification," he said. "It might be that nobody can change [the time], there might not be enough time, for many reasons.
"But for [the] Villarreal [game], it could have been changed. Villarreal and the television companies wanted to. Only LaLiga didn't. There was no justifiable reason."
Ancelotti categorically denied that the Brazil Football Confederation (CBF) had contacted him in recent days over coaching the national team, following Brazil 4-1 defeat to Argentina in World Cup qualifying.
The Italian has previously been strongly linked with the position, but has a contract at the Bernabéu until June 2026.
"My contract speaks for itself," Ancelotti said. "I don't have anything to add. I have a lot of affection for the Brazil team, its players and fans. But I have a contract at Real Madrid."
On Thursday, UEFA announced that it was investigating four Madrid players -- Kylian Mbappé, Vinícius Júnior, Antonio Rüdiger and Dani Ceballos -- over their behaviour following their penalty shootout victory over Atlético Madrid in the Champions League round of 16 on March 12.
Real play Arsenal in the quarterfinals next month.
"We trust UEFA to do what they have to," Ancelotti said. "We believe [their behaviour] was all correct. The players celebrated. We'll wait for UEFA to say something. We're confident it will all turn out OK."
