Before the rain could drench Pittsburgh's Heinz Field, Manchester City poured in the goals at the home of the Pittsburgh Steelers.
The reigning English Premier League champions crushed AC Milan, 5-1, in Group B of the International Champions Cup Sunday.
After the first 10 minutes saw the Rossoneri start bright, the Citizens capitalized in the 11th minute by way of Stevan Jovetic. The forward cut through a pair of Milan defenders to finish off a cross from Jesus Navas, who delivered the ball perfectly from the right wing.
The scoring continued for City just two minutes later, when Scott Sinclair collected the ball in the box off a Gael Clichy cross to beat Michael Agazzi. To anyone paying attention, AC Milan's struggles were glaring.
Ten minutes later, Manuel Pellegrini's side struck for a third goal, as Navas sent a shot into the left side of the net after taking a deflection off Andrea Poli. City's offensive onslaught continued in the 26th minute, when Kelechi Iheanacho sent a toe poke past Agazzi.
The 17-year-old found a small bit of space in between a few defenders to slot home the fourth goal scored by Manchester City in their first game of the competition.
AC Milan finally got one back in the 42nd minute, as Sulley Muntari tapped in a ball at the left post after Alex Rodrigo Dias da Costa headed a corner to that area of the box.
Filippo Inzaghi's side did test City keeper Willy Caballero 10 minutes earlier on a shot in front of the goal by Stephan El Shaarawy, but the new addition to the goalkeeping force on the blue half of Manchester made a terrific reaction save.
Once the first half ended, play was suspended due to inclement weather in the Pittsburgh area. The game eventually resumed after a 30-minute delay to the start of the second half.
As the skies began to clear up, Milan started the second half well, but it was Jovetic who once again killed their momentum with a 58th-minute goal.
After the fifth City goal found the back of the net, not too many chances were created. But Caballero was forced into a kick save on a shot from M'Baye Niang in AC Milan's last noticeable effort of the day.
Manchester City will look to earn their second win of the tournament Wednesday against Liverpool at Yankee Stadium, while AC Milan will not play again until Saturday against Liverpool in Charlotte.
Key Player Grades
Stevan Jovetic, F, Manchester City: A-
Jovetic put together a pair of solid goals for City to prove to Pellegrini that he is deserving of more playing time throughout the rest of the team's American tour.
His movement and accuracy may not be enough to challenge Sergio Aguero or Edin Dzeko for a starting spot, but he definitely left a good mark on his manager with his performance Sunday night.
Michael Agazzi, GK, AC Milan: D
Agazzi had a rough day in net for the Rossoneri, as he not only let in five goals but also had some poor positioning. His biggest error came on the third City goal when he did not defend the near post as the ball deflected past him.
Jesus Navas, M, Manchester City: B+
Navas was a force up and down the right wing for the entire first half for the Citizens. He created plenty of opportunities moving forward, and he helped open the scoring when Jovetic converted on his pass.
Inzaghi mentioned in his press conference what has been made clear about the Serie A sides playing in America right now:
