LONDON (AP) — Chelsea and Barcelona traded first-half goals in a 1-1 draw Thursday as both teams stayed unbeaten in the Women's Champions League. Chelsea thought it had a go-ahead goal in the 83rd minute on substitute Catarina Macario's header, but she was ruled offside and Sonia Bompastor’s team ended the night in sixth place with eight points from four matches. Ellie Carpenter scored in the 16th minute at Stamford Bridge, but Chelsea's lead was short-lived.
