Liverpool manager Jurgen Klopp believes Daniel Sturridge is now ready to be unleashed to help their final push for Champions League qualification.
At the other end of the table Hull City were relegated back to The Championship after being humbled 4-0 by Crystal Palace.
Liverpool travelled to the capital knowing any slip-up could let Arsenal take the initiative in the race for a top-four finish, and faced a West Ham team who had dashed Tottenham's even loftier ambitions just nine days earlier. I'm pretty sure they'll want to enjoy football at Anfield, they'll want to try anything and that makes life hard for us. Not definitely, but they must be confident now. We scored the goals, controlled the game, could have scored more often but that's completely OK that we didn't. There is much to build on for the next season - if Liverpool can keep him.
The double from the Brazilian global against West Ham took his tally to 13 goals and nine assists from 34 appearances in all competitions this season. Subs: Sofiane Feghouli (for Calleri, 55mins) 5, Ashley Fletcher (for Fonte, 55mins) 5, Robert Snodgrass (for Ayew, 77mins) 5. Subs: Grujic 6, Lucas 6, Woodburn 6.
Should Arsenal draw or lose, Liverpool will know a slip-up against West Ham would not necessarily be fatal.
Liverpool would make the Hammers pay for blowing that clear opportunity, as the visitors started the second half clearly the better side.
Goals from both Sturridge and Origi should give renewed confidence to a front line that has struggled for goals in recent weeks. West Ham's three-man defence, fresh from shutting out Everton, Stoke and Spurs, were threatening to the same to Liverpool. Coutinho scores - Wijnaldum crashes a shot against the crossbar with a spectacular volley.
The Brazilian stepped inside two defenders on the edge of the box and coolly placed the ball past Adrian.
As a centre-forward, he's been superb, dovetailing well with wide players, linking up with midfielders-particularly compatriot Philippe Coutinho-and chipping in with a handful of important goals.
"Can we work on different things with Phil?"
Coutinho weaved his way through exhausted West Ham bodies before finally beating Adrian with a fine, low drive.
Wtf! Why doesn't Origi pass Sturridge?
Having initially led the counterattack himself, Coutinho received the ball back from Wijnaldum before skipping past James Collins and finishing powerfully from close range.
It will not be easy, but if Klopp's men perform like they did today, there is no reason why they can not take the full three points to polish off a much improved season.
