"It was a strange day for every football supporter, a surprise. We heard about the Super League the past few months but I was sure it was not going to happen," Ancelotti told reporters ahead of Friday's Premier League trip to Arsenal.
"The 12 clubs were wrong. They didn't take into consideration the opinion of the players and managers and the supporters.
Everton midfielder James Rodriguez scored on his return after more than six weeks out due to injury but the home side were denied the win thanks to a late goal from Michy Batshuayi.
*"I think the position in Europe is still there because we're in the fight and we have a game in hand," Ancelotti told reporters.
"No I'm not worried, because Joao is young, a goalkeeper without experience, but he has a lot of quality. I'm not worried for the absence of the two goalkeepers," Ancelotti told a news conference.
"I'm not complaining for the players that are not available. It'll be a difficult game, but I don't think it's an easy game for City. They have better quality than us, but I'm sure they will have a difficult game.
A Ben Godfrey own goal and a second-half penalty from Jorginho stretched Chelsea's unbeaten run under Tuchel to 11 games while Everton slipped to sixth.
"We have the quality up front but always it comes through the passes," said Guardiola. "We need a little bit more patient, the second goal is an example of that. In the end we have to try and get the players up front in a better position."
