The West Ham striker is starting to show some potential.
But it might just be bad news for Andy Carroll in the long run.
Indeed, this was only a cup clash against Championship opposition. Yet Emenike still showed exactly what's needed of a prolific goalscorer.
Apart from missing his chance to net a hat-trick, the 28-year-old displayed predatory instincts. He was always forward, always in the right position and ready to tuck the ball into the back of the net - even if from only a couple of yards.
When Emenike was brought to West Ham, he had potential. His pace and goal record suggest he could be the Hammers' top goalscorer if he fulfills that potential.
It's been a steady start but Sunday showed what he can do. If he carries on - staying at West Ham beyond this season - he could end up West Ham's first-choice striker.
But where does that leave Carroll? With Sakho, Valencia and Emenike, West Ham will have three versatile forwards who score goals. Carroll, however, can only really play one way and is constantly suffering from injury problems.
Should Emenike keep his form up, then, could Carroll end up West Ham's fourth-choice forward?
