Proven at Premier League level
Hernandez arrives at West Ham as someone that has already shown his qualities in the Premier League and should be able to make an immediate impact.
The Mexico international enjoyed a superb spell at Man United earlier in his career and won two Premier League titles.
He scored 59 goals in 158 appearances at Old Trafford, which is superb considering he was often used as an impact substitute.
Hernandez’s pace and work-rate has already proved a success in England, meaning he should hit the ground running at the London Stadium.
