The Baggies haven't won a league game since a 1-0 away win at Burnley in August, but Pardew's men will hope to turn over a new leaf and kickstart 2018 the right way with a rare away win.
Here's how West Brom could line-up as they travel to the London Stadium on Tuesday:
Ben Foster is expected to keep his place between the sticks.
After utilising a five-man defence against Arsenal, West Brom are expected to return to a 4-4-2 formation at the London Stadium.
Removing Craig Dawson and swapping Matt Phillips with Allan Nyom at right-back should be all that's needed, with Kieran Gibbs, Jonny Evans and Ahmed Hegazi all expected to remain.
West Brom will likely field a four-man midfield on Tuesday. Due to the fact that the Baggies only had a two day rest period ahead of their trip to the capital, Gareth Barry will likely be switched for the return of Grzegorz Krychowiak, while James McClean may feature on the right wing.
With Salomon Rondon a doubt, the front two of Hal Robson-Kanu and Jay Rodriguez is the most likely option. Rodriguez has been the marginally more in-form striker of the two, but typical of the Baggies this season, both have been average at best. The two forwards have scored a measly five league goals between them.
