But Capello believes both men have lost control and that fellow Italian Conte may have underestimated how well Portuguese Mourinho handles the press.
“I think Conte didn’t realise who he was up against,” Capello told Sky Sport Italia.
“It’s the Chelsea shirt which makes managers nervous. Remember how wound up Mourinho got when he was Chelsea manager? Conte’s just doing what Mourinho used to do.
“We all remember Mourinho on his knees in the middle of the field, running wild after his side won.”
Conte and Mourinho have been arguing since the Portuguese suggested his rival was a “clown” for being so animated on the touchline.
Conte responded by saying Mourinho was “senile” and “a little man” for making references to the Italian’s ban in Italy over alleged match-fixing, which he was later exonerated in 2016.
“They’re completely out of their minds,” said former Real Madrid manager Capello, now coaching in China with Jiangsu Suning.
“I never thought it could get this far. But remember, when you wind Mourinho up, he’s very clever in these debate situations. Maybe once again he just wants to divert the attention from his team.”
“I don’t think that Conte has realised who he has been dealing with yet. In my opinion, he should have said just one thing. If Conte used the ‘senile’ word he certainly made a mistake.”
Meanwhile, former Manchester City manager Roberto Mancini believes the feuding pair will soon make up.
“You’ll see, they’ll meet and it will end up with tarallucci and wine,” the Italian told Gazzetta dello Sport.

They also failed to score at Norwich on Saturday, prompting an FA Cup third-round replay next week.
“Against Stoke we scored five goals but against other teams we have maybe missed too many chances,” Courtois told chelseafc.com.
“Like 2-2 at the Emirates (on January 4) and 0-0 last night and at the weekend against Norwich, maybe we have to score more goals from the chances we create because I think we create enough danger, but we need to finish it as well.”
Defender Antonio Rudiger added in the London Evening Standard: “I think the last pass is missing, the final part to score the goal. There weren’t a lot of chances against Arsenal but some were there. We have to kill a match off.”
Chelsea head coach Conte insisted it was not merely the forward players who are culpable, pointing to two missed headed chances by defender Andreas Christensen against Arsenal, who host the second leg on January 24.
“We are conceding less than last season, but we are not scoring like last season. We have to improve,” Conte told Chelsea TV.
Despite Conte’s comments and his support for Alvaro Morata, it appears the Spain striker is feeling the burden of expectation.
Morata scored seven goals in his first eight appearances following his £58million move from Real Madrid, as a replacement for Diego Costa, but he has since netted just five times in 21 outings.
Rudiger added: “As a striker it’s normal that you want to score. Of course there are times when the head is down a little bit.
“I’m not worried about him. The whole team is with him and I think all the fans are with him.
“It’s just a difficult period for him. Sometimes there are spells when you score and don’t score, but his effort for the team is good and he always tries. If he scores again, everything will be fine.
“Can he win the second leg against Arsenal for us? Definitely. We saw it in the last round against Bournemouth. He had one chance and scored. When he does this again, everything will be OK.”
Arsene Wenger has defended Alexis Sanchez and insisted the Arsenal forward’s omission from the starting line-up at Chelsea was “nothing to do with the transfer market”.
The former Barcelona forward is out of contract in the summer and is free to speak to foreign clubs over a pre-contract agreement, while he has been repeatedly linked with a switch to Manchester City.
Speaking after the Carabao Cup semi-final first leg stalemate at Stamford Bridge on Wednesday night, when Sanchez came off the substitutes’ bench, Wenger said: “People don’t know Alexis Sanchez. This is a guy completely focused on playing football.
“The performance of Alexis Sanchez and the commitment does not depend on the duration of his contract, just depends on the fact when he’s on the football pitch he wants to play.
“He can make a difference between what’s going on outside and what’s going on on the football pitch.
“When you come on to the pitch you play football and give 100 per cent. That’s what he does.”
Wenger maintains hope Sanchez will stay.
“I want him to stay for longer,” he added.
“I have no problem if he signs with us now or in June.”
Alex Iwobi did start, despite facing a fine for partying prior to last Sunday’s FA Cup third-round loss at Nottingham Forest.
“If I think he can help the team to win, that’s nothing to do with the fact he can be punished separately individually,” Wenger added.
Wenger felt the familiarity of the teams, meeting for a second time in two weeks, contributed to the tepid draw.
Jack Wilshere went off with an ankle sprain which could make the midfielder doubtful for Sunday’s trip to Bournemouth.
The Video Assistant Referee was available in English football for the second time.
The most relevant moment of its use came when Cesc Fabregas wanted a penalty following a Danny Welbeck challenge after 88 minutes, but play continued after referee Martin Atkinson consulted VAR Neil Swarbrick and it was determined Welbeck got the ball.
Wenger felt the game had advanced from that moment, as more than a minute elapsed before the VAR was consulted at a break in play for a corner.
He added: “It looks a bit strange to go on for two minutes sometimes and after come back.
“That you cannot intervene straight away is a bit frustrating.”
Chelsea head coach Antonio Conte felt more added time should have been applied due to VAR.
Conte also bemoaned another goalless draw, after last Saturday in the FA Cup at Norwich.
Conte said: “We shot 20 times. We created chances to score, but we didn’t take them. I think in the last period we must be more clinical.
“My speech is not for the strikers. We have to improve with all the players, not only the strikers or midfielders.”
