Jelena Canković starred as Chelsea won a ninth straight Women's Super League game by edging out Reading in a five-goal thriller at Kingsmeadow.
In snowy conditions, the Blues scored three times before the break with Cankovic at the double. Reading did score twice in two minutes near the hour mark to threaten a fightback. However, Emma Hayes' team saw out a nervy finish to restore their three-point lead at the top of the table.
It was a crucial win for the defending champions who know they return after the WSL Christmas break for a crunch London derby with Arsenal in the New Year.
