With just 11 games left in the top flight, none of the teams behind Manchester City can afford to slip up.
While Pep Guardiola’s side have all-but wrapped up the Premier League title, the battle for a top four finish is certainly not over.
Just four points separate Manchester United in second and Tottenham in fifth with Liverpool and Chelsea sandwiched in between.
Liverpool are in action against West Ham today (3pm) while Tottenham take on Crystal Palace tomorrow (12pm) before United face Chelsea.
And if results pan out a certain way there could be just two points between all four teams come Monday.
Mourinho could be up against it to pull off a result at home to Chelsea tomorrow as he will be without five key players to choose from.
Marouane Fellaini, Marcos Rojo, Phil Jones and Zlatan Ibrahimovic were already ruled out prior to this week.
But Mourinho has confirmed Herrera, who was forced off after just 17 minutes against Sevilla earlier this week, could be set to miss up to six weeks of action.
“Ander is out,” said Mourinho. “I don’t know the final diagnosis but I know he’ll be out for a few weeks.
“I don’t know how many is a few – two, three, four, five, six weeks – I don’t know, but a few weeks, for sure. Coming back from injury – nobody else.”
