The visitors will be looking to provide the reigning champions with a tough test after losing just one of their last five matches.
Match preview
After losing to Barcelona in the Champions League semi-final, Chelsea looked set to experience more frustration in Wednesday's home league meeting with Liverpool.
Niamh Charles managed to restore parity after Liverpool took the lead in the second minute, but finding a winner was proving to be a tricky task.
Chelsea's relentless pressure eventually told as Sam Kerr netted an 86th-minute winner to claim three crucial points.
The Blues may be sitting in third position, but they have two games in hand over league leaders Man United, who are four points better off than Emma Hayes's side.
The West London club know that if they win their final five league games then they will be crowned champions for a third consecutive season, and after winning their last 12 home league games, Chelsea will be confident of claiming another victory on Sunday.
After losing 3-2 to Brighton & Hove Albion, Everton came out the right side of a five-goal thriller in their most recent outing against Reading.
The Toffees were left with a mountain to climb when Reading's Justine Vanhaevermaet scored a brace in the opening 17 minutes, but Everton fought their way back thanks to a Hanna Bennison strike and a Katja Snoeijs penalty, before Nicoline Sorensen completed the remarkable turnaround with an 83rd-minute winner.
Sixth-placed Everton are sitting in a comfortable midtable position, but Brian Sorensen will be challenging his side to close the three-point gap to Aston Villa, who are in fifth position and have played a game more.
However, with the Toffees set to face three of their traditional top-four sides in the WSL run-in, they will have to be at their very best if they are to consistently pick up points between now and the end of the season.
Ahead of Sunday's trip to the capital, Everton can draw inspiration from the fact that they have avoided defeat in four of their previous five away matches.
