This is a difficult one to choose but, for reasons not entirely of his own doing, the most disappointing player of West Ham United’s 2017-18 campaign has to be Javier Hernandez.
When he arrived from Bayer Leverkusen last July, it seemed that after years of searching the Irons had found a striker who almost guaranteed goals.
Successful spells at Manchester United, Real Madrid and then in the Bundesliga cemented the Mexican’s reputation as a man who knew exactly where the back of the net was.
Fast forward 10 months and Hernandez is going into the World Cup on the back of a season in which he scored just eight times in the Premier League.
Put into context, the 29-year-old’s record is actually not that bad; he only started 16 games in the top flight, his other 12 appearances coming from the bench.
It seemed obvious almost from the outset, though, that West Ham’s style, or lack thereof, would not suit Hernandez’s natural poaching instincts.
This is a player who thrives when given a sniff of a chance in the penalty area, but his team-mates were not equipped to work the ball into the danger box.
When David Moyes took over from Slaven Bilic, the Scot decided that an even more direct approach was required which focused on exploiting the pace and power of Marko Arnautovic, whom he converted to a central striker to essentially replace Hernandez.
Chicharito was reduced largely to substitute outings and even a run of three goals in four Premier League matches after the turn of the year could not cement him a place in the team.
Yes, there were question marks over his attitude, particularly after he was strongly linked with a move in January, but perhaps the truth of the matter is that he arrived at the wrong club at the wrong time.
If deployed in a system designed to play to his strengths, Hernandez is one of the most lethal finishers in the game.
However, Moyes’ decision to rely instead on Arnautovic’s talents paid dividends and it is difficult to argue against it.
Hernandez did about as well as he could in the circumstances and so the disappointment is perhaps more that West Ham had a forward who is one of the best at what he does, but were not able to capitalise on his attributes.
For whatever reason, sometimes a move just does not work out and unfortunately that seems to be the case here.
