BIRMINGHAM, England - A brilliant second-half strike by Chelsea midfielder Conor Gallagher secured a 2-2 Premier League draw with Aston Villa on Saturday as the Blues staged a thrilling comeback from two goals down to threaten Villa's Champions League hopes.

Villa are fourth on 67 points, seven ahead of Tottenham Hotspur, who play title-chasing Arsenal in the North London derby on Sunday as one of their three games in hand over Villa. Chelsea are ninth on 48 points.
