Chelsea boss Jose Mourinho will make a late decision on whether to bring Diego Costa back into his first team for the trip to Leicester City on 29 April but he will have Oscar available.

The Blues can lift the Premier League title in front of their own fans on 3 May if they collect three points at the King Power Stadium and beat Crystal Palace.

Loic Remy is ruled out of the match against Nigel Pearson's resurgent Foxes and Mourinho could recall Costa to his starting line-up but admits his injury history makes the decision difficult.

"I don't know [whether Costa will play]," Mourinho told a pre-match press conference. "I have to think about it, if it deserves a gamble of if we should wait a few more days to be sure. If it was a player without an injury history I'd play him tomorrow but because of his history I will think about it. We need five or six points, if we can get three on Wednesday that will be good for us."

In the absence of Costa and Remy, Mourinho opted not to start a recognised centre forward in the 0-0 draw with Arsenal on 26 April, with Oscar instead playing in the most advanced role.

But the Brazil international was taken off at half-time after a nasty collision with Arsenal goalkeeper David Ospina.

Mourinho confirmed the 23-year-old will travel to Leicester for the game but could not say whether he would play. He said: "I don't know, I know he is not in hospital he went to his house and slept home last night. I'm not sure if he was concussed by we saw his face was swelling and at half-time we subbed him, we didn't want to take the risk. Everyone travels [to Leicester], even the ones not table to play."

Injuries to his first-team forwards have prompted suggestions that 17-year-old Dominic Solanke may have a role to play before the end of the season. But with Chelsea in FA Youth Cup action against Manchester City in the second leg of the competition's final on 27 April, Mourinho will not call upon any of his young starlets for the Leicester game.
