Sam Kerr was the difference-maker once again as Chelsea edged past Aston Villa to reach a third successive Women's FA Cup Final.
It was a cagey first half at the Poundland Bescot Stadium, with Magda Eriksson sliding in to prevent the prolific Rachel Daly from opening the scoring and Zecira Musovic saving from Lucy Staniforth to keep the scores level heading into the break.
Jelena Cankovic rattled the crossbar with a well-taken effort less than a minute into the second half before Alisha Lehmann skimmed the side netting after some excellent work down the right flank.
