Leicester City's defeat at Swansea saw Nigel Pearson's side drop to 17th in the Premier League table, just one point outside the relegation places.
James Sharpe looks at five lessons learned from the trip to south Wales.
1. To get the best out of Jamie Vardy, he cannot be stuck out wide. He is at his best when he is running at the heart of a defence, committing defenders and latching on to through-balls, exploiting space in behind. Vardy had just 18 touches in the 67 minutes he was on the field at Swansea – the lowest of any City starter.
2. Leonardo Ulloa's start to his first Premier League campaign has been one of completely differing fortunes. He was labelled as one of the bargains of the transfer window after scoring five goals in his first five games – a mere snip at £8million. But in the four games since, he has failed to register even a single shot. That is clearly not good enough for your main striker. But Ulloa is a striker who needs service. He is not like Vardy, who can run through a defence or outpace a defender. He needs crosses. But he also needs to be in a position to receive them.
3. Win your home games, they say. That is the key to survival. Anything you get on the road is a bonus. At the minute, these bonuses are few and far between. Just one goal away from home, despite it leading to victory at Stoke, is a concern. That has now put more pressure on City's home form. Their performances at the King Power Stadium have been impressive – they are unbeaten, but with only one win. With West Brom and Sunderland next up at home, turning performances into results is now imperative.
4. There has been a distinct lack of cohesion since City's victory over United. The rhythm and tempo has not quite been there. But the side has been unsettled, too. In the four games since United, four of City's five central midfielders have started at least one. There have been three different combinations, with Danny Drinkwater being the only constant. Andy King, the only one not used, started the first four. All five of City's central midfielders featured at Swansea. Is it time just to find the best combination and stick with it?
5. Some goalkeepers will find any excuse to keep a clean sheet. Before the Swansea game, Kasper Schmeichel and his young stand-in Adam Smith told manager Nigel Pearson they thought the goals at the Liberty Stadium were too big. Pearson told the officials and out came the tape measure. They were fine.
