Pep Guardiola called on Manchester United to give Erik ten Hag time to implement his ideas ahead of his first Manchester derby meeting with the Dutchman.
Ten Hag, who worked with Guardiola when he coached Bayern Munich's second team between 2013 and 2015, will lead United at the Etihad Stadium for the first time on Sunday.
With Manchester City in imperious form, Ten Hag will look to avoid following the example set by United's last five managers (David Moyes, Louis van Gaal, Jose Mourinho, Ole Gunnar Solskjaer and Ralf Rangnick) – all of whom lost their first Premier League clash with City.
United are enduring a five-year trophy drought and have yet to mount a serious Premier League title challenge since Alex Ferguson's retirement in 2013, and Guardiola stressed the importance of allowing Ten Hag time to cement his approach and style of play.
"We know each other a little bit from Munich but he has done an incredible job across Europe, so I can't say anything else," Guardiola said of Ten Hag.
"Everyone knows it depends on results, if you win in the big clubs you have time, if you don't win you are in trouble."
Asked whether United's run without silverware made Ten Hag's task more difficult, Guardiola said: "I don't know, imagine if you took over after winning the Premier League and Champions League, maybe it might be tougher. But I don't know, the more you do well the better.
"The result is a part, but the club has to watch training, how they handle problems and whatever, but if they trust [him] then give time.
"In football, like many things in life, it needs time. If you change managers often it is difficult."
Guardiola also revealed he enjoys a friendship with United legend Ferguson, adding: "We went for dinner once or twice, and we send messages, he is always so nice to me.
"Not before a derby! But when we play at Old Trafford he has a box, and he offers me wine and I have loads of respect. He is a legend and I like having that relationship."
Meanwhile, speculation has cantered on whether Guardiola's own spell in Manchester, in which he has delivered four Premier League titles and five domestic cups, could soon be over, with his contract set to expire at the end of the campaign.
Guardiola is yet to agree to fresh terms, but does not expect City to struggle whenever he eventually departs, adding: "The club knows exactly the target for the next step.
"There will not be a problem. They know what they have to do. When the club depends on one person there are problems, but we have solid foundations.
"If the club just depends on Pep, we are not doing well."
City have won their last seven Premier League home games, scoring three or more goals in each of those victories.
The last English team to win eight successive top-flight matches while scoring three or more goals in each was Tottenham, who did so between March and September 1965.
While City will have one eye set on matching that feat, another win over United would be their 18th in the Premier League, the joint-most any team has claimed against the Red Devils in the competition (also Chelsea and Liverpool).
'I have nothing against him' - Leao brushes off rumours of feud with Fonseca
Rafael Leao has shrugged off suggestions of a feud between him and Milan head coach Paulo Fonseca despite starting fewer games in recent weeks.
The winger started three consecutive Serie A matches on the bench after the last international break, coming on to make substitute appearances in two of those.
He returned to the starting line-up for their 3-3 draw with Cagliari last time out, netting twice in the first half to bring his tally up to three goals for the season, and 50 overall in Serie A.
Leao has also provided three assists in the Italian top-flight, while he has both attempted (36) and completed (24) the most dribbles of any Milan player in the competition.
There were reports of tension between Leao and Fonseca due to the former's lack of playing time in recent weeks, but he brushed off the idea.
"These things happen during the season, I have nothing against him, and he has nothing against me," Leao said while at Portugal's training ground.
"It's all settled. I don't like being on the bench, obviously, but he makes the decisions and I, as a player, have to respect the coach.
"When I step onto the pitch, I have to do my best to help the team."
Leao has also impressed with performances in the Champions League this season, especially against Real Madrid in a 3-1 win, as he registered an assist for their third goal.
However, he has also come under criticism in Italy, with one pundit claiming he has a poor work ethic, suggesting he only puts in effort in big games.
"Clearly, I do not agree with that," Leao added about the recent comments.
"I have been having a great season at Milan but, like everyone else, there are ups and downs. The campaign has only just started. Look, I know that I am not the perfect player and sometimes I can do much better.
"I am not shaken by this criticism. I have people who help me to improve and those are the ones I have to listen to. This criticism just spurs me on to respond on the pitch."
Australia 0-0 Saudi Arabia: Visitors denied last-gasp winner on Renard's return
Saudi Arabia had a stoppage-time goal ruled out as Herve Renard's first game since returning as Saudi Arabia head coach ended in a 0-0 draw against Australia in World Cup qualifying.
Sultan Al-Ghannam fired through a sea of bodies in the 94th minute of Thursday's Group C contest at AAMI Park, but the celebrations were cut short due to an offside infringement.
Referee Ali Saeed Al Naqbi had earlier irked the home side by awarding a 12th-minute penalty for an Ahmed Al-Kassar challenge on Mitch Duke, which was then overturned.
Replays showed the incident happened just outside the box, but Australia felt the Saudi keeper should have been sent off and not issued just a yellow card.
Joe Gauci pulled off a fine double save later in the first half, albeit the offside flag later went up, but it was Australia who did more to win the game prior to the late drama.
Brandon Borrello was played clean through on goal and opted to square to Riley McGree, who was unable to help the ball past covering defender Saud Abdulhamid in front of goal.
Data Debrief: Another blank for both sides
Australia entered this game without a goal against Saudi Arabia in 2,716 days - a run that will extend for a little while longer after this latest blank.
The Socceroos have failed to score in three of their five third-round qualifying games, while Saudi Arabia have gone three in a row without netting.
Tony Popovic's side will justifiably argue they did more to win the game, though, finishing with an expected goals value (xG) of 1.31 to Saudi Arabia's 0.05, but the teams remain locked on points in Group C.
Carsley focusing on positives after nine England drop-outs
Lee Carsley wants the England players at his disposal to "make the most of the situation" after nine others dropped out through injury.
Everton defender Jarrad Branthwaite on Wednesday became latest player to withdraw from the Nations League games with Greece and Republic of Ireland.
Trent Alexander-Arnold, Cole Palmer, Phil Foden, Jack Grealish, Bukayo Saka, Declan Rice, Aaron Ramsdale and Levi Colwill have also dropped out.
England captain Harry Kane has admitted to being unhappy with the large number of withdrawals for interim boss Carsley's final two games in charge.
However, Carsley attempted to put a positive spin on the situation when speaking at his pre-match press conference on Wednesday ahead of facing Greece.
"The focus all camp has been on the players that are here and it's important that we make the most of the situation," he told reporters.
"With the amount of players that have pulled out, it gives other players an opportunity to be here.
"We're really looking forward to the game and it's going to be a tough test for us and the focus has been purely on the players that are here.
"With the amount of pull-outs we've had in the window, historically it's been like that in the past - November has always been a challenging window.
"But the culture that Gareth [Southgate], Steve [Holland] and the rest of the lads created has made it a really positive environment and the players that are here thoroughly deserve to be here."
Grealish was one of the first players to withdraw from the squad, having been called up despite not playing for club side Manchester City since 20 October.
City boss Pep Guardiola questioned England's decision to include Grealish in their squad as he recovers from injury, but Carsley insisted he was justified in doing so.
"The medical teams are constantly talking throughout squad selection, regardless of whether there are games or not," Carsley said.
"We are constantly getting updates. The medical departments have brilliant communication between club and country.
"It was always the case we were going to get the players who were potentially going to miss out in to the assessed. Jack was one of them. He was assessed and sent back and it was as clear as that."
England trail Group B2 leaders Greece by three points with two rounds of fixtures to play, having lost the reverse fixture 2-1 at Wembley last month.
The Three Lions have won on all four of their previous trips to face Greece, doing so by an aggregate score of 9-1 - only against Luxembourg (5/5) do they hold a better 100% win rate away from home.
However, Greece are on the longest active winning run of any European nation in all competitions (five games) and could win six consecutive matches for the first time November 2013.
Carsley, who will step aside for Thomas Tuchel after next week's home match with Republic of Ireland, said: "We're expecting a tough game against Greece and it’s one we have to win.
"But we're really looking forward to it, we've had a good week's training, the players are in good spirits and it's going to be a sell out with a great atmosphere.
"We've had to wait four or five weeks for this, but this next window is so important to us, not just tomorrow but Republic of Ireland as well, so it's a great challenge for us."
