Pep Guardiola's side are embroiled in a tense battle for a top five finish in the Premier League and De Bruyne lifted them to third place with his first half strike at the Etihad Stadium.

For just the second time in a turbulent campaign, City have reeled off five successive wins in all competitions.

It was a major boost to City's hopes of securing a place in Europe's elite club competition.

"We are better than we were weeks ago. If we play like we did today, it is really good but we cannot relax. Winning in that way is good because it will make us realise that we still need to work," Guardiola said.

After 10 years with City, it was De Bruyne's penultimate appearance at the Etihad after the midfielder was told he will not get a new contract when his present deal expires at the end of the season.

It was only the sixth goal this season for the 33-year-old Belgian, underlining why Guardiola has decided to release him after an injury-plagued decline over the last two years.

But De Bruyne's contribution could be crucial for City, who have three matches left and hold a four-point advantage over sixth-placed Nottingham Forest, who play their game in hand against Crystal Palace on Monday.

Fourth-placed Newcastle and fifth-placed Chelsea also have a game in hand over City heading into the weekend's fixtures.

Hinting he could stay in the Premier League after leaving City, De Bruyne said.  "A lot of teammates have said that it's sad I have to go, but that's just how it goes sometimes in life.

"I don't know what the future will be, but I know that I can still play here. I try to play as much good football as I can. I'm still enjoying it."

Guardiola saluted De Bruyne, saying: "Just thank you. His contribution in the game against Crystal Palace when we were 2-0 down and he delivers, and today the goal again.

"I want the best for Kevin. It cannot be possible to have done these many years without him.

"He has been an incredible player but the situation is what it is. It's almost impossible to replace this kind of player."

- De Bruyne makes his point -

Even qualifying for the Champions League and winning the FA Cup final against Crystal Palace will not salvage the season in Guardiola's eyes after their four-year reign as English champions came to a limp end.

Surrendering the title to Liverpool was bad enough, but missing out on a place in the Champions League for the first time since 2010-11 would be a complete catastrophe and this result kept them on course to avoid that fate.

Guardiola sprang a surprise by naming Erling Haaland as an unused substitute as the Norway striker returned ahead of schedule from the ankle injury he suffered at Bournemouth in March.

Wolves arrived buoyed by six successive top-flight victories for the first time since 1970-71 and their confidence was clear after such a successful streak.

Not for the first time this season, City were creaking at the back.

They rode their luck to escape as Rayan Ait-Nouri fired against the post from close-range before his effort from the rebound was cleared off the line by Josko Gvardiol.

Guardiola's men recovered their composure and the breakthrough came in the 35th minute with the kind of flowing move that has been City's trademark in De Bruyne's decade in Manchester.

Ilkay Gundogan made a break from midfield and slipped his pass to Jeremy Doku, who deftly eluded his marker before pulled the ball back to the unmarked De Bruyne.

Having cleverly found space just inside the Wolves area, De Bruyne held his nerve to slot past Jose Sa, a finish that showed City what they will miss next season.

Wolves still carried a threat and Matheus Cunha rattled the post with a stinging strike from the edge of the area in the second half.
