The Citizens are currently sat in fourth place in the WSL table, while the hosts are four points worse off in sixth position.
Match preview
Paul Konchesky will be satisfied with West Ham's performances in the first half of the season, with their 10 league games split evenly between wins and defeats.
As a result of winning two of their last three league games, West Ham ended 2022 in fifth place, although they have played one game more than the teams around them in the league table.
While the Hammers have signed Amber Tysiak during the transfer window, Grace Garrad, Claudia Walker, Alex Hennessy and Thea Kyvag have all left the club.
Although West Ham begin the new year with a difficult home game against a Manchester City side chasing Champions League qualification, they know that a win would move them to within one point of their opponents.
The hosts can draw inspiration from the fact that they have won four of their six home games in all competitions this season, including their last two home matches.
City began the WSL season with two consecutive defeats, which ultimately put them on the back foot from the outset, but they have managed to remain in touch with the top three thanks to an impressive run of form.
After losing to Aston Villa and Chelsea in September, the Citizens recorded six consecutive league victories, scoring 17 goals and only conceding on three occasions in that period.
Their winning run was ended by their local rivals Manchester United in their final WSL game of 2022, but a second half equaliser from Laura Coombs ensured the derby fixtures finished in a 1-1 draw, which extended City's unbeaten league run to seven matches.
However, the draw prevented City from closing the three-point gap to United, who occupy the third and final Champions League place.
Although both of their defeats in the topflight this season have taken place on their travels, Gareth Taylor's side have won their last three away league games, and they will be determined to begin the new year with another win on Sunday.
