The Blues had to grind out the victory against a Tottenham team who were a threat throughout, but thanks to some excellent defending, the early goal proved enough.
It was City's tenth Premier League win in a row.
At a sun-drenched and colourful Etihad, City began looking for an early lift to quickly banish Wednesday’s crushing disappointment.
But it was Spurs who came close to opening the score after just three minutes as the dangerous Son Heung-Min found space on the left before dropping a shoulder and firing a powerful drive that Ederson beat away.
City, however, drew first blood just two minutes later.
The effervescent Bernardo Silva cut inside a couple of challenges before spotting Sergio Aguero’s clever movement, crossing the ball to the Argentine who headed across the six-yard box for Foden to nod home his first Premier League goal.
It was exactly the start had City needed in what was already proving to be another bright, open game.
Yet Spurs again came close on 14 minutes when Christian Eriksen was played through and Ederson again did well to deny the visitors.
If there was any fatigue in the legs of the City players, it wasn’t showing and Bernardo’s twinkle-toed run into the box should have earned a penalty on 20 when a clumsy Jan Vertonghen challenge brought down the Portuguese in the box – but referee Michael Oliver wasn’t interested – where’s VAR when you need it?
The Blues were dealt a huge blow just before the break when Kevin De Bruyne was taken off after looking as though he jarred his knee taking a shot – hopefully the injury isn’t anything too worrying.
On half-time Son span away from a number of challenges before running 30 yards and again seeing his effort saved by Ederson.
More hard work, it seemed, lay ahead in the second-half.
The pattern of play continued with Lucas Moura driving through the middle within the first 30 seconds of the re-start, but the danger was snuffed out by the City defence.
There was yet another controversial decision that didn’t go the Blues’ way on 51 minutes when Aguero’s shot hit one arm, then the other of grounded Toby Alderweireld in the six-yard box, but again the referee thought otherwise.
In the baking sun, the game ebbed and flowed, with the Blues still wary over Spurs' tactic of playing the long-ball over the top to Son and the home defence had to be resolute and focused throughout.
But as the clock ticked down, so the nerves of the City fans were understandably frayed.
But the Blues dug deep and despite the tension in the dying moments, clung on for three crucial points to end an emotionally draining win in style.
"It was a real tough game after mental defeat on Wednesday. The last two days, really tough for us. They qualified for the Champions League and couldn't lose anything today. We could lose the Premier League.
"This kind of game after Wednesday was really tough.
"I could not have done what the players done. Ederson saved our game. It's three more points and it's still in our hands."
What it means…
City go back to the top of the Premier League, a point clear of Liverpool who play Cardiff City tomorrow.
