How have the West Ham players fared so far this season? We had a go at rating every member of the squad.
Adrian 8 - The Spaniard finished as runner-up in last season's Player of the Year awards voting at Upton Park, and has continued to impress this season. The 28-year-old has produced some remarkable saves to keep West Ham in games this season, as well as scoring the winning penalty in an FA Cup shoot-out against Everton. A real cult hero at West Ham, Adrian will be in the running to their Player of the Year again.
Jussi Jaaskelainen 5 - it's hard to really grade someone who has played 27 minutes of Premier League football this season, but he deputised well for Adrian after his sending off at Southampton in February. Offers experienced cover in the West Ham squad, but given that he turns 40 this month, the Finn may not be at Upton Park much longer.
Carl Jenkinson 8 - snapped up on a season-long loan from Arsenal last summer, Jenkinson has been superb at right back for West Ham. The 23-year-old has been solid defensively, as well as effective going forward, and should be back in the discussion for an England call-up. Fans will want to see him sign permanently after his excellent loan spell.
Guy Demel 5 - the Ivorian has offered decent depth behind Jenkinson at right back but in his limited action on the pitch, it's clear that he doesn't provide quite as much as Jenkinson does. Still a valuable squad member, Demel doesn't have the technical ability to be more than cover at Upton Park, and has had a fairly average season to date.
James Tomkins 8 - a product of the West Ham youth system who has really taken the next step this season. Previously thought of as a decent centre back, Tomkins has impressed this term, arguably overshadowing team-mate Winston Reid at times. A really strong season for Tomkins, and fans will be hoping he continues that next season rather than it being a flash in the pan.
Winston Reid 7 - penned a new contract with the club earlier this year, and that's great news for West Ham and their supporters after another solid campaign from the New Zealander. Has suffered with a few injuries this term which hasn't helped him, but he has still been impressive in the West Ham defence, and looks to be a key player that the Hammers will build around in the future.
James Collins 6 - has provided really valuable depth at centre back for West Ham throughout the season, filling in whenever Reid or Tomkins have been out injured. The 31-year-old Welsh international has just a year left to run on his contract, and needs to prove his worth again next season in order to earn a new one.
Aaron Cresswell 8 - few could have expected Cresswell to have transitioned to the Premier League so easily after his move from Ipswich Town last summer. The 25-year-old has made the step up from the Championship with no trouble at all, proving his worth with great crossing and attacking play from left back. Will be a key player for West Ham moving forward after a superb debut season.
Joey O'Brien 5 - much like Demel, O'Brien has provided depth at full back and even at centre back on occasion, but isn't good enough to be relied upon long-term. With just six Premier League starts, O'Brien has certainly been a bit-part player, but he's trusted by Sam Allardyce when injuries occur.
Alex Song 7 - a marquee signing having arrived from Barcelona on a season-long loan, Song was superb in the first half of the season, dominating the midfield and proving why Barcelona signed him in the first place. Yet in the second half of the season, Song has seemingly taken his foot off the gas, and has struggled to impress - meaning a permanent stay is looking unlikely now.
Mark Noble 8 - Mr. Consistent in the West Ham midfield, Noble has enjoyed another fine season for the Hammers, chipping in with one goal and three assists. A vital player at Upton Park, Noble is unlucky to have once again missed out on an England call-up - and it's hard to see what Roy Hodgson doesn't like about Noble after another superb campaign at Upton Park.
Cheikhou Kouyate 8 - the Senegal international arrived from Anderlecht last summer and has instantly taken to Premier League football, earning comparisons to former Arsenal legend Patrick Vieira in the process. Athletic and often dominant in midfield, Kouyate has demonstrated why Allardyce was so keen to sign him, and has even filled in at centre back at times, proving his versatility.
Kevin Nolan 5 - with just one goal and one assist, it's been a tough season for Nolan. Normally so important under Allardyce, Nolan has struggled to make an impact this time around, and at 32, it seems that he just isn't the player he was anymore. West Ham often play poorly when he's on the pitch, and it doesn't feel like that's much of a coincidence.
Morgan Amalfitano 7 - the Frenchman is a strange case. So influential when coming off the bench but often quiet when handed a start, Amalfitano has shown flashes of his quality in the West Ham midfield, and deserved to play more regularly. Maybe we'll see that next season, after Amalfitano penned a new two-year contract to stay at Upton Park last month.
Nene 4 - the Brazilian signed in February, but has made just four substitute appearances and played just 50 minutes of action for West Ham. Only on a contract until the end of the season, it's hard to see him earning a deal to stay at Upton Park for next season and beyond after an ineffectual stay so far.
Stewart Downing 7 - much like Song, Downing was superb in the first half of the season, flourishing at the top of West Ham's midfield diamond. Yet in the second half of the campaign, Downing has been quiet - and with just one goal and two assists in 2015 compared to four goals and six assists in the first half of the season, it's tough to say what has happened to Downing since the turn of the year.
Matt Jarvis 4 - just three starts in the league this season underline how Jarvis is struggling at West Ham right now. The former Wolves man has offered nothing to the cause this season and it wouldn't be a surprise to see him sold on this summer after a totally ineffectual campaign, in which the midfield diamond rendered him redundant.
Andy Carroll 6 - it's hard to grade Carroll because when he has played, he's been great. Five goals in just 14 games was a strong return, and his display against Swansea was excellent, completely dominating the Swans defence with two goals and 15 headers won. Yet, as always, the problem with Carroll is injuries. His absences have cost West Ham, so it's hard to give him to high of a grade for this season.
Carlton Cole 4 - it's difficult to see what Cole really offers to West Ham except hard work and aerial ability. With just two goals this season, Cole has been a fringe player, but when he has played he hasn't impressed. May be needed as cover but much like Jarvis, it wouldn't be a shock if he left Upton Park this summer.
Diafra Sahko 8 - a roaring success since his move from Metz. With 12 goals in 24 appearances, the Senegal international has been prolific, and has far exceeded expectations having been an unknown upon his arrival. Now West Ham's main striker, Sakho will be relied upon heavily in the future, including next season after a superb debut campaign.
Enner Valencia 7 - arrived as a big signing after impressing at the World Cup with Ecuador last summer, and whilst West Ham fans rate his pace and work rate, he has scored just five goals in 30 games this season. He'll likely improve that next season, so this has been a pretty solid first season in England for Valencia.
Mauro Zarate 5 - offered fleeting signs of his ability after his move from Velez Sarsfield, but ended up as fourth choice behind Carroll, Sakho and Valencia by January, and was then farmed out to QPR on loan in the winter transfer window. May flourish under a new manager at West Ham, but already appears to be on borrowed time at Upton Park.
