The Hammers have had a dream Premier League campaign so far after coming close to relegation last season.
David Moyes has worked his magic to say the least, and the Irons are just two wins away from a possible Europa League place with their Champions League dreams being dashed over the last month.
Form has dropped ever so slightly for the Irons recently having managed just one win in their last five games, with their only three points coming away at Burnley.
Said Benrahma picked up his first goal in West Ham colours with a fantastic strike to salvage a point last week against Brighton and Hove Albion, a point that could prove vital in the race for Europe.
For West Brom they will be looking to end the season with pride having already been relegated from the top flight, a first relegation from the Premier League for former Hammers manager Sam Allardyce.
The Baggies are heading into tonight's game on the back of a 2-1 loss at the hands of Liverpool thanks to a last minute header by Reds keeper Allison.
Issues at both ends of the pitch have been Albion's problems all season long, finding the back of the net 33 times, which is the third lowest in the league behind Sheffield United and Fulham.
Defensively they have looked better in recent weeks but still struggle and tonight will be about trying to keep a clean sheet and help Allardyce identify who might leave and who could stay in the summer if the 66 year old is to stay at the Hawthorns.
Having fans back in attendance will be a massive boost for both teams, with Tuesday night seeing fans return to Premier League games for the first time since Everton faced Southampton on December 12th 2020.
One of West Ham's star players this season has been Tomas Soucek who arrived at the London Stadium last January initially on a loan deal from Slavia Prague.
The 26 year-old has been ever present in the Hammers midfield this season finding the back of the net nine times, Soucek is optimistic that his side can make European competition next season.
"We want to prepare for both of the games." Soucek told WHU.com
"We started to think about European football a few months ago, and now our dream is still alive, so we want to prepare for West Brom, and the need three points because we need to know our schedule and our position at the table, so I ask our team that we beat them.”
David Moyes has praised the recent performances of West Brom ahead of tonight's clash and that despite being relegated his side need to not be disrespectful and to put in a performance.
"What we need to do is go there and play and get back used to it, but Sam Allardyce has come in and steadied West Brom and got them very close to being safe," Moyes told WHU.com
"I think it would be completely wrong and disrespectful to expect any club in the Premier League, because they are relegated, makes you feel like they are not trying as hard or working as hard.
"You only need to look at Sheffield United’s result the other night against Everton to know that right up until the last minute it is tough and it doesn’t matter who you are playing.
"Everybody wants to win, so the competition is really difficult. West Brom played really well against Liverpool and were really unfortunate not to take something from the game the other night."
5,000 fans are expected to be at The Hawthorns on Wednesday evening, the last time the Baggies players experienced a crowd was back in December at Anfield where they drew 1-1 with Liverpool. Sam Allardyce knows that the fans will make all the difference come 20:15pm.
“I think the fans can make a huge difference." Allardyce told WBA.
“We’ve certainly missed them and the encouragement they give us this season.
“I’m sure the players will have the hair on the back of their necks sticking up when they run out on to the pitch on Wednesday night because it has been that long since we’ve had supporters inside a stadium."
The last time the two sides met was back in January with Jarred Bowen and Michail Antonio finding the back of the net as the Hammers picked up a 2-1 win at the London Stadium.
In the last ten meetings between the two sides they are level on wins at three a piece with four draws.
