On 15 July 2013, Gerrard signed a contract extension with Liverpool. On 3 August 2013, Liverpool played Olympiacos, against whom Gerrard scored arguably his most celebrated goal, at Anfield for Gerrard's charity fund-raising testimonial match. Liverpool won the match 2–0, in a game where past players such as Jamie Carragher and Robbie Fowler made appearances. Alder Hey Children's Charity, of which Gerrard is a founding partner, received £500,000 from the proceeds. On 16 September, Gerrard captained Liverpool for the 400th time in a 2–2 draw at Swansea City. On 5 October, Gerrard scored in a 3–1 win over Crystal Palace, becoming Liverpool's first ever player to score in 15 successive league campaigns, overtaking the record previously set by Billy Liddell. Also in October 2013, he became the longest-serving Liverpool captain, 10 years after his appointment by Gérard Houllier on 15 October 2013, breaking the previous record held by Alex Raisbeck, who captained Liverpool from 1899 to 1909.
