Matty Cash's brilliant first-half goal earned Aston Villa an excellent 1-0 win over Manchester City, whose Premier League title hopes took an early blow.
Cash fired home from the edge of the area in the 19th minute and that proved enough for a fourth league win in a row for Villa, who celebrated Unai Emery's third anniversary in charge in style.
It was a third successive home victory over Pep Guardiola's side, who fell six points behind leaders Arsenal and face the prospect of another hunt of Mikel Arteta's side after Christmas.
