Man City vs Leicester City: preview
After 36 Premier League games this season for Pep Guardiola's Manchester City side, with 30 wins, two draws and four defeats, it's tonight's game as Leicester City travel to the Etihad Stadium which has been singled out by many as decisive in what's become a fascinating Premier League title race between City and Liverpool.
Indeed 'The Foxes' are one of the four sides to have triumphed against City in the corresponding fixture played at the King Power Stadium winning out 2-1 on December 28th (2018).
The maths are simple, City control their own Premier League title fate with wins over Leicester and at Brighton will see the "Citizens" once again crowned champions as challengers Liverpool can only look to beat Wolves and hope that one of the two sides in blue and white can do Jurgen Klopp's side a favour.
In his pre-game press conference City boss Pep Guardiola acknowledged how difficult this season has been: "It is the toughest league I've ever played as a manager," he stated. "There are no doubts. "That's why being there is incredible. Only one will take the prize.
"You have to give credit to how huge our rival is. In my career as a manager, we have played against incredible sides. One is Luis Enrique's Barcelona with Leo Messi, Luis Suarez and Neymar, and the other is Liverpool. "They are the best two sides I've played as a manager. Last season was incredible but this season, we are up against an incredible team.
"They're physical and have improved their positional game, and defensively, they concede few goals. That's why I'm so delighted." concluded the Catalan coach.
