Chelsea interim manager Guus Hiddink says it feels strange to have little to play for the rest of the season.
The Blues will almost surely miss out on a place in next season's Champions League and can only hope to qualify for next season's Europa League.
They will be boosted by the return of striker Diego Costa who returns after his three-game suspension.
"Normally when a player is out for that long a period they have a tendency to take a break, but he [Diego Costa] didn't," Hiddink said.
"He has been working very hard, including individually when we were on the road. He was here at Cobham working on his own with the staff. He is very eager to play.
"It's been strange [having little to play for lately] because this club is used to being involved for some titles in the last weeks and months of the season, and after the defeats in the Champions League and the FA Cup there was a little bit of emptiness because there was no silverware to go for.
"When it's not happening you feel it for a few days, but then you have to regather and refocus yourself and the team as well.
"What I have asked from them is to go in to tomorrow's match and the rest of the matches with ambition and desire to get a good run going in the last games.
"I would like to finish my spell now at Chelsea in the last games with the players showing their quality – from the mental side of things as well.
"[Manchester] City tomorrow have had a beautiful week after getting in to the semi-finals. It's good for them to be in the last four and it's a reward for their efforts over the last seasons.
'Their team is getting into a certain flow of success and results so they'll like to continue it. It's encouraging for them and for us it is another reason why we expect very strong opposition."
