Pep Guardiola has no doubt Antonio Conte can lead Tottenham to sustained success, but only if the Italian gets the backing he needs.
Spurs boss Conte this week appeared to suggest his playing resources had been weakened by trading in the January transfer window.
Conte clarified his position on Friday when he stressed that was only a view he took in terms of squad numbers, saying the arrivals of Dejan Kulusevski and Rodrigo Bentancur from Juventus had in fact improved the quality at his disposal.
While Conte insisted Spurs chairman Daniel Levy knows his true thoughts, the merest implication of any unhappiness from the head coach has come at a bad time, with the team on a three-game losing run in the Premier League.
They have gone down to Chelsea, Southampton and Wolves, dealing a blow to hopes that Conte might lead the team to a top-four finish and a place in next season's Champions League.
Now Guardiola's Manchester City await Spurs on Saturday at the Etihad Stadium, in the ultimate test for any English team.
City have lost just one of their last 11 home league games against Tottenham (W8 D2), going down 2-1 in February 2016. However, they did lose the reverse fixture on the opening weekend of the season.
Guardiola spoke of his admiration for Conte, saying on Friday: "If the club rely on him 100 per cent, they will have success.
"My first season here was tough in terms of results. Every manager needs time, he needs investment, he needs many, many things to be there for a long time or have success, especially in this country.
"All the managers need time. Unfortunately in football we don't have time. I had time, the club gave me this time, that's why I will always be grateful, but all the managers need time to make plans and try to convince the players to follow what you feel."
Guardiola said being a head coach in England was "more difficult than any other part of the world". But he believes Conte has demonstrated with Juventus, Chelsea and the Italy national side that he is a coach who consistently improves teams.
"I have incredible respect for the fact when I watch his teams I feel there's something new I can learn and I can improve," Guardiola said.
Tottenham have scored just 17 times in the Premier League from an expected goals (xG) total of 23.2 since Conte took charge at the start of November. Over the same period, City have scored 40 goals from an xG tally of 33.5.
Replying to comments from Conte in which he labelled Guardiola the world's best coach, the City boss added: "Thank you so much, but I am not. I appreciate it, but I'm not."
Spurs have won three of their last four Premier League games against City, as many as they had managed in their previous 13 against them. However, these last three victories have all been in home games.
Should they pull off the league double this term, it will be the first time Spurs have achieved that against reigning English top-flight champions since they beat Liverpool 1-0 home and away in the 1986-87 season.
City have taken 43 points from the last 45 available, roaring away at the top of the table, but Guardiola says a wounded Spurs could make his task complicated.
"This is the problem, the fact they've lost three times in a row it will be more difficult tomorrow, for sure, 100 per cent," he said.
"It's difficult for top teams to lose four times in a row. They have a lot of weapons. We know how with Son [Heung-min] we've suffered, with Harry Kane, with [Lucas] Moura. They have a lot of quality."
