City show no sign of slowing up in their bid for an unparalleled quadruple, with Wednesday's emphatic 5-1 win at 10-man Tottenham sending them top of the Barclays Premier League.
The result extended their unbeaten record in all competitions to 20 matches - a run which includes 18 victories and quite remarkable 69 goals.
Such success is thanks in no small part to the incredible attacking options at their disposal, such as Spain international Navas.
The diminutive winger once suffered with chronic homesickness but in the summer swapped Sevilla for not-so-sunny Manchester, where he is loving life on and off the pitch.
"I am really happy here in England. I have settled down very, very well both on a professional level and personal level," Navas said through a Spanish interpreter.
"All of my team-mates help me very much in adapting to a new league, a new style of football.
"On a personal level, I have my family here, my wife, my daughter, so I am extremely happy.
"I love football and enjoy playing football. That's why I came here. I am very happy and cannot complain.
"We are enjoying the style a lot, not only the players but also I think the fans.
"We have to keep working like this, working really hard and, if we do it like this, then we are going to get the same results."
Few look capable of stopping the City behemoth, although if one man can it is likely to be Jose Mourinho.
The Portuguese takes Chelsea to the Etihad Stadium on Monday, when Pellegrini's 100 per cent Premier League home record will come under its toughest inspection yet.
Navas faced Mourinho's Real Madrid during the pair's time in Spain and is all too aware what to expect.
"If you want to challenge for all the titles, you have to be ready for this type of weeks or months that are very demanding and you have very important matches," he said.
"But we are working really hard and I think we are prepared to face any team.
"Mourinho's teams work especially hard, all the players.
"He has a special, winning mentality so it is always difficult to face teams that Mourinho manages."
