Manchester United have one of the most expensively assembled attacking units in world football but all is not well for the Old Trafford stars.
Their wealth of talent has been questioned in recent weeks and were tested again at Upton Park, coming up short as Daley Blind was the man to provide a last-gasp equaliser.
Although the Red Devils captain has been operating in a deeper role in recent months, the England skipper is still yet to have a shot on target in 2015 and Louis van Gaal must be worried that he is losing out on having Rooney in a position where he can really hurt the opposition.
In fact he proved more of a thorn in his own side's defence as he lost Cheikhou Kouyate for the opening goal and gave away possession cheaply on more than one occasion.
ANGEL DI MARIA
United's club-record signing has not scored a league goal since October and has still not fully adjusted to the new, more central role given to him by van Gaal.
He fizzed a shot straight at Adrian as half-time approached but is far too often a peripheral figure for a player who cost so much and carries a reputation as a match-winner.
The emergence of the Belgian winger was one of very few positives of David Moyes' ill-fated United reign but he has flattered to deceive this season and has scored just once in the last 13 months.
With little contribution he was hauled off to make way for compatriot Marouane Fellaini as United chased the game.
Much has been made of the Monaco loanee's lack of goals and, despite adding a fourth of the season against Leicester last weekend, he still seems a yard off the pace.
Hit a tame effort wide shortly after West Ham went in front and wasted a superb chance after combining with van Persie - poking wide when clean through - and United still are yet to see the best of the Colombian.
ROBIN VAN PERSIE
Making his 100th appearance for United, the Dutchman has himself admitted he needs to score more goals having been unable to return to the prolific levels that clinched the title in Sir Alex Ferguson's final season.
Caught a sweet volley that was kept out by Adrian, who also kept out a late, low effort - van Persie was sharp at times but still remains a shadow of his former self.
