Guardiola is the first Spaniard to win the English title. For West Brom (20th place; 21 points), they are on the verge of being relegated, so this is a must-win match if they are to have any chance of surviving.
Here, we look back at some of the key factors behind a dominant triumph. They can surpass Chelsea's Premier League record of 30 (2016-17) by winning three of their remaining five fixtures. England winger Sterling, so often criticised for being a wasteful finisher, became City's clutch player. The worlds best pulled off another magnificent save to deny Sergio Aguero levelling the derby at 3-3 last weekend.
City were without Aguero, who had sustained a rib injury in a auto crash, but Kevin De Bruyne made sure the Argentina striker wasn't missed as he slammed in the victor in the 67th minute. A dutiful cog in the machine during the opening weeks, the Belgium midfielder kicked into gear and City's season duly took flight.
The Baggies could not claim the win their performance deserved after they outplayed the Swans for much of this match.
"Our Time. Our City". It is a level he has maintained with startling regularity. "The amount of goals, chances and points, to do that in the Premier League, with the contenders we have, is because the players are so good". The Belgian scored in the return fixture against the Baggies in December past year and will be hoping to do more damage against his former side at Old Trafford on Sunday. Darren Moore's side has a -26 goal differential on the season and have not won a match since January.
902 - The number of passes completed in a one-sided 1-0 victory over Chelsea in March represented a new benchmark since Opta began recording the data in 2003-04.
"It's not just two games, it's about the course of the season and the quality football that City have played game after game".
Having bent most weeks of the season to their will, City picked a bad time to falter at the beginning of April.
Jose Mourinho revealed that the FA Cup semi-final against Tottenham Hotspur weighed on his mind as he chose to drop Eric Bailly for Manchester United's Premier League clash with West Bromwich Albion. Defensive weaknesses were exposed to offer rivals encouragement for next season but it was an unusual slump.
Mourinho, though, was quick to dampen talk that United had handed the title to City, insisting it is their dominance over the season that secured their coronation. With 3 of these 5 wins coming against sides settled in the league's top-five positions, they can't be accused of achieving this the easy way. In fact, they have scored 12 goals in the past five league matches, and the team is now riding a five-game winning streak. West Brom are the bottom team and that indicates how important and decisive the game will be for them; they need points.
