Schwarzer became the oldest player to represent Chelsea in the Premier League when he played against Sunderland on 19 April 2014, aged 41 years and 195 days old. He became the club's oldest ever player by some margin, overtaking Graham Rix, who last played for Chelsea at the age of 37 years and 203 days. On 22 April, he replaced the injured Petr Čech in the first half of a Champions League semi-final against Atlético Madrid, and kept the score at 0–0. On 27 April, he started against Liverpool at Anfield, a crucial game for Chelsea to stay in the title race. He kept a clean sheet and made some outstanding saves to deny Liverpool from equalising, with Chelsea winning the game 2–0. His clean sheet against Liverpool was his 150th Premier League clean sheet, a feat only two other goalkeepers have achieved so far, those goalkeepers being Čech and David James.
