The former defender feels the West Ham forward hasn't been good enough.
Pearce has also emphasised the obvious point that the Hammers have struggled with injuries to Andy Carroll and Diafra Sakho.
Jelavic, however, hasn't featured or scored regularly since moving to West Ham during the summer window's Deadline Day and the pundit subsequently feels the acquisition of Emenike is a logical one.
Pearce told Sky Sports News on Monday Morning: "With the injuries, they’ve had, it's a good move. Jelavic hasn’t really had an impact. So it makes sense to sign Emenike."
If the 30-year-old can be seen as a poor signing, is it really his fault?
West Ham needed cover on Deadline Day and went to Championship side Hull to sign a striker who hasn't exactly been prolific of late.
Jelavic has done a job and few should criticise him personally.
As such, a move away from West Ham makes sense, while Emenike - if he settles in the Premier League - should definitely be considered an upgrade.
