The Nigerian has had a tough route to the Premier League.
The Nigerian arrived at the club on loan from Fenerbahce at the start of the month to provide cover in an area where injuries have been commonplace this term.
He has so far looked a tad rusty on the pitch and West Ham fans are probably wondering who they have signed and if he can cope with the pressures of the Premier League.
One thing for sure, he is used to overcoming greater adversity than this.
Speaking to The Sun this week he has spoken about his extremely eventful career to date.
In 2011, whilst playing with Turkish outfit Karabukspor, he was embroiled in a match-fixing scandal which saw him imprisoned for four days.
Speaking about this he stated:
“My time in prison was a crazy nightmare that I couldn’t wake up from. I’ve never committed a crime in my life, but I was treated like a criminal, living on bread and water.
“It was not a good experience. It gave me a different perspective on life.
“When I was finally cleared I thanked God for letting justice prevail."
He also spoke about the time in 2015 that he was on the Fenerbahce team bus that was shot at by a gunman, stating:
“I was on the phone to my brother when I heard a loud bang. The bus suddenly swerved and there was panic.
“I instinctively took cover and our security officer told us the driver had been shot. Seeing him covered in blood was scary."
This from a player who also slept on a restaurant floor in order to pursue his dream of professional football in South Africa.
Emenike has not hit the ground running at West Ham, but you would be hard pushed to find a player who has stood up to challenges more in his football career than this striker.
In time, that adversity will stand him in good stead at the Boleyn Ground.
