Wayne Hennessey's howler gifted Aston Villa their first league win since August as they edged out Crystal Palace 1-0.
The goalkeeper fumbled Joleon Lescott's second-half header into his own net as Remi Garde claimed his first victory at the 11th attempt.
It was also redemption for Lescott who was accused of playing a game with chewing gum - to the fury of fans - while a substitute during Saturday's 1-1 FA Cup draw at Wycombe.
And the defender gave Villa much to chew over even if their first home league win of the campaign failed to lift them off the bottom of the Premier League. Wilfried Zaha hit the post for Palace inside the first minute but the Eagles deserved nothing from a limp performance.
Palace never got as close again as it woke Villa up. Hennessey then handed them the winner on 58 minutes with a monumental error.
Villa had been pressing and won a corner and, despite Lescott's header flying straight at Hennessey, he spilled it through his legs and over the line.
