The Premier League was established in 1992, after 25 years has witnessed the ascension of 6 champions including Manchester United (13 times), Chelsea (5 times), Arsenal (3 times), Manchester City (2 times), Leicester City and Blackburn Rovers all have won the title once.
In the case of the team that has won the most championships ever, M.U, they have only led the rankings 5/13 times after Christmas and won the championship at the end of the season. Looking at the big picture, in the past 25 seasons, there have been 11 teams at the top of the rankings after Christmas, but only less than half of them have been crowned.
As for Manchester United under Sir Alex, they have only topped the table 7 times but have won 13 times. However, since this veteran strategist retired, M.U has not even topped the table at any Christmas season since 2013.
In the past 25 years, there have been only 13 years that the team has topped the rankings after Christmas and won the championship at the end of the season, a fairly high rate (about nearly 50%). But that is not why Manchester City this year under Pep Guardiola is afraid. Because, by round 20, the Etihad team was 14 points ahead of M.U and there was no sign of slowing down in terms of form.
All the statistics up to this point are... statistics for Manchester City. Although the Premier League champion at Christmas is not sure to take the throne at the end of the season according to historical records, with what he has in hand, Pep and his team are looking to create an absolute season. And who knows, they could win the Premier League Gold Cup like Arsenal did 14 years ago.
