For Nigeria's forward Victor Moses and his team mates to have any hope of playing in the Champions League next season, they must get the maximum points this afternoon.
A week on from throwing away all three points from a winning position against Tottenham Hotspur, Rudiger acknowledges that lessons must be learnt if his side are to have any hope of making up the 10-point deficit on Spurs in fourth place.
However, they have not lost in 11 home Premier League games against the Hammers (W8 D3).
'The thing is we have to look we have start to play good football and win games.
"In this case, if we wanted to reach a place in the Champions League [we have to win], because the other teams are clinical".
"It gave us all a boost to win last weekend. This is very important for me, for my staff and for the players, also because the supporters deserve at least this".More news: Cuba Marks World Health Day with Great Achievements

"We looked unsafe in the second half", said Hart.
Hazard was at his mesmerising best after just four minutes, weaving past a host of Hammers players before flashing a shot agonisingly wide of Hart's right-hand post.
West Ham, now six points clear of the relegation zone, were ecstatic to escape with a point despite a largely limp display.
Chelsea face Southampton next Sunday in their FA Cup semi-final at Wembley Stadium but even if they were to go on and win the competition, it would be scant consolation in the eyes of Azpilicueta. "They created a lot but we stood strong". It was an emphatic performance in the first half and it gave us the chance to go on and win the game quite well. The Hammers shocked Chelsea in their last game with a goal from Marko Arnautovic but Conte's side will be out for revenge.
Michail Antonio is the only man to drop out of their XI from a vital 3-0 victory over Southampton, with an unfortunate hamstring injury having brought his season to a premature conclusion.
