As expected, the English champions made a bright start but unfortunately, they were reduced to 10 players after Sophie Ingle was sent off, having brought down Ajibade in the 12th minute.
Deyna Castellanos failed to convert from the spot as the Spanish failed to profit from their numerical advantage in the first half.
After holding out for 13 minutes, Maren Mjelde broke the deadlock for Chelsea from the spot in the second half after Aissatou Tounkara caught Sam Kerr inside the area in the 58th minute.
Five minutes later, the hosts extended their lead when Fran Kirby fired past goalkeeper Hedvig Lindahl into the bottom corner.
