As the Premier League now stands, a Liverpool victory over already relegated Middlesbrough at Anfield on Sunday will secure a fourth place finish and will guarantee the Reds a Champions League playoff, which they must win to make the group stages of Europe's elite competition.
Guardiola's City are now two points above Liverpool with a superior goal difference, so if they can only draw at Watford and Liverpool win at home to Middlesbrough, there is a chance the clubs could tie for third and face a play-off for the spot in the Champions League group stage.
Going into the last round of fixtures, the three teams - occupying third to fifth place - are separated by just three points with similar Goal Difference (GD) and Goals Scored (GS).
The Premier League table as it stands. If City draws 3-3 at Watford and Liverpool wins 3-0 at home, then both teams will finish on 76 points with 78 goals scored and 42 conceded. Each position in the league is worth an additional £1.9 million thanks to the new TV deal - Chelsea will earn £38 million for finishing top, while the bottom club Sunderland will earn the minimum... That being said, if they have saved their best performance for the final day of the season, Arsenal fans will be hoping the play-off is scheduled for Friday 26 May.
