Nottingham Forest boss Oliver Glasner, speaking to BBC Match of the Day: "You can never plan to win 3-1 against [Manchester] City because are so good.
"But today, especially the players and our fans deserve this win because they were so passionate from the first minute, scoring nice goals.
"We had moments to suffer but then we could rely on our fans pushing us, supporting us. Amazing goals and such a great team effort today so really proud.
"I think we've had better performances in possession because today we rarely had the ball. Regarding the team spirit, the energy, I think it was our best game.
"The way we play football I think we've had many better games but how we defended, how passionately we defended, how tactically smart we defended, it was one of our better games."
On outrunning City: "I think it is the only way you can beat Man City. They're so good, such great players, such a good structure and they move the ball so quickly. They can play through the middle, they have incredible dribblers on the wing and they have such pace. Then, of course, they have Haaland in the middle.
"You should control everything and if you want to control it, you have to run because you have to be so quickly aware.
"Of, course you can just defend but you also need to go forward and this is what we did today in the right moments, we scored the goals in the right moments and credit again to the players."
On Liam Delap: "When you come in with a price tag on your back everybody believes 'if you pay so much, he has to score all the goals'.
"I would say it's Liam's second regular Premier League season because he didn't play a lot at Chelsea. He had one great season at Ipswich then lost a lot of confidence at Chelsea, so now he's getting better and better into rhythm.
"These goals are his biggest strengths with his right and his left, also using his power and his strength. We knew that he would score goals for us and today, they were nice ones."
Nottingham Forest striker Liam Delap speaking to BBC Match of the Day: "We've been performing well over the last few weeks just not been ruthless enough - today showed what we can do when we are ruthless.
"Three good finishes - Jair [Cunha] the first one as well. So important to get a good start.
"As a striker it's the most important thing [to score goals] - the only thing you're judged on. You can play well and not score, really nice to score. Got to keep performing and improving but today I'm happy.
"We know we will suffer against a team like City. We had in our minds we need to fight, to run, we outrun them and we won duels. We got chances on the counter and the match plan was bang on and everyone did really well - it was top."
On what Oliver Glasner said last week: "It's football. You have good and bad days and we had a fun Sunday but it probably brought us together. We have been working so well for the last few weeks. That was a poor performance but we've showed we can bounce back and the spirit and belief in the group is as high as ever."

Liam Delap has scored three goals in nine Premier League games for Nottingham Forest this season, more than he did in 28 appearances for Chelsea last term (one). His brace today was just his second in the Premier League, after September 2024 for Ipswich against Aston Villa.
Forest scored more goals in this match (three) than they had in their previous six home league games combined (two). This was also the first time they'd scored three goals in a Premier League game against a side starting the day in the top two.
