Interim boss Frank Lampard has backed Raheem Sterling to prove he is still one of the world's best against Real Madrid.
The England forward has struggled since his £47.5million move from Manchester City.
Lampard recalled Sterling in his first game back but the wideman could not stop Chelsea slipping to a 1-0 defeat at Wolves in the Premier League on Saturday.
Sterling has scored just seven goals this term but netted the crucial opener in Chelsea's 2-1 aggregate win over Borussia Dortmund in the last 16 of the Champions League last month.
