The Blues' hopes of qualifying for the Champions League took a huge blow at the weekend as they lost 1-0 at home to Manchester United.

Chelsea has lost, and failed to score, in each of its last four league games; only in November 1912 have the Blues ever endured a longer such run.

They are seven points behind fifth-place Liverpool, which occupies the final Champions League spot, and just three ahead of 12th-place Fulham.

Rosenior admitted Chelsea has not played well enough in recent games, shouldering the blame for his side's poor form.

"We have to win. That is what this club demands and rightfully so, and that is what the fans expect," he said. "It is about winning football. That is what football is about. You can't speak about the long-term if you aren't doing the job in the short-term.

"Being really respectfully honest here, we haven't done well in recent games and that is on my shoulders as the head coach of the team.

"We have a huge game and then an FA Cup semi-final. That is why you are in football, but now is the time to deliver and that is what we have to work towards."

There is added pressure on Chelsea ahead of its trip to the Amex Stadium, with Brighton just one point behind the Blues.

The Seagulls twice came back from behind in a 2-2 draw against Tottenham, keeping them in a strong position to push for a European place.

Brighton boss Fabian Hurzeler has encouraged his side to embrace its fixture against Chelsea, seeing it as a chance to grow.

"I am impressed by the character and resilience the team have shown, especially the players, how they stick together, how they hold each other accountable, how they work in every training session," Hurzeler said.

"It's a position we should really embrace, we have all worked hard for [it].

"Now we need to enjoy these moments and games because it's a great opportunity for us to grow.

"We want to enjoy it. We want to be very humble starting this game, we want to start with intensity and energy. Hopefully, we get a positive result."
