After a summer spending-spree, West Ham United will be bitterly disappointed at their pointless start to the Premier League season. They lost their first three games of a campaign previously filled with excitement after lavish recruitment under Manuel Pellegrini.  

Indeed, after spending over £100m on new players in the summer, the Irons board surely expected at least a top-half finish from Pellegrini as a minimum, perhaps even pushing for European contention, thus far, that looks a pipe-dream. The East Londoners have not only lost, but certain players have put in very poor performances that will be very concerning to the Hammers faithful. In particular, a 2-1 loss at home against Eddie Howe's Bournemouth will be of particular concern, as that is a game Irons fans would have likely thought their team should be winning.

To pinpoint one player who has the potential to really cost the London Stadium outfit, attention has to be turned to club-record signing Felipe Anderson. The Brazilian is valued at £31.5m by Transfermarkt. The right-sided midfielder was surely expected to be a world-beater, but has so far showed he is a precarious talent who can drift in and out of games, and has often failed to make an impact. If he doesn't turn his form around, he could really be the single player who costs the Irons dearly. Manuel Pellegrini likely pinned a lot of hope on the player to be both a creative and goal-scoring threat in the side.

The West Ham United support will be desperately hoping their record-signing is just finding his feet in the Premier League, and is about to set the division alight once he gets used to the pace of the English game.
