One mistake during a 38-game season does not decide who wins the title, but Steven Gerrard will be haunted for the rest of his life if Liverpool does not win the Premier League.
His slip just before half-time last Sunday enabled Djemba Ba to give Chelsea a lead at Anfield which became 2-0 in the final minute with a goal by Willian, who Liverpool tried to sign last summer.
It is 24 years since Liverpool won the title and this season presented its best chance of breaking the stranglehold of Chelsea, Manchester City and Manchester United.
