The two Manchester clubs, United and City, will be looking to maintain their places at the top of the Premier League by winning their respective matches this weekend.
Sir Elton John was pictured with Pep Guardiola on Saturday ahead of Watford's home Premier League encounter with Manchester City, and he may well have been seeking answers in the sky after the Hornets were swept away.
Speaking after the game, Guardiola said: "It was so good".
Aguero was in uncompromising form in front of goal once again, and he has now scored nine goals in six games against the Hornets.
The Portuguese pulled off an incredible display against Liverpool in a insane 3-3 draw to start the season, with last weekend's long-range efforts from Abdoulaye Doucoure and Daryl Janmaat against Southampton bringing their fans another three points to cheer.
Watford withstood City's early pressure, with goalkeeper Heurelho Gomes saving well from Fernandinho and Christian Kabasele making a superb tackle to deny Aguero a one-on-one after 18 minutes.
When you watch Manchester City play, you might not witness a close match, but chances are you'll witness an entertaining one.
Aguero is now into his seventh season with City, and has helped them to two Premier League titles and two League Cup wins. I am learning a lot from them and I hope I can learn much more.
"We know how much quality we have", said the 26-year-old Belgium worldwide.
Watford have played the 4-3-3 formation in three of their games before going to a 4-2-3-1 when visiting the Saints, and picking up their second win.
Aaron Mooy's Huddersfield team held on for a 1-1 draw against Leicester City to be fifth on eight points but should have gone behind late in the game if not for a complete whiff from Foxes striker Jamie Vardy.
Silva will be forced to field a makeshift back four in a repeat of last season's final game against the same opposition. His men will have to be at the top of their game throughout the match in order to get all three points.
