Five conclusions from West Ham's 2-1 defeat with Arsenal on Sunday afternoon.
West Ham manager Sam Allardyce recently said that his goalkeeper Adrian was up there with compatriot David De Gea in terms of the top goalkeepers in the Premier League.
Today, the former Real Betis stopper certainly proved his worth with a string of fine saves to keep Arsenal at bay in the second half as West Ham pushed forward and got caught on the break.
West Ham missed Carl Jenkinson
Given that he's on loan from Arsenal, right back Carl Jenkinson was ineligible for the game, leaving Allardyce to look for alternatives at full back.
In came Joey O'Brien, but the Irishman was poor, with substitute Guy Demel not faring much better. Neither could replicate the attacking prowess of Jenkinson, with delivery from the right hand side inconsistent throughout. Today was the day where we found out how important Jenkinson truly is to the Hammers.
Winston Reid blew his Arsenal audition
Having impressed with West Ham, defender Winston Reid has been linked with likes of Arsenal, Liverpool and Manchester United, with his contract expiring in 2015.
However, any possible audition for a move to Arsenal was blown by the New Zealander today, who struggled to cope with Arsenal's attack. Having given away the penalty, Arsene Wenger may look elsewhere now.
Allardyce needs to go back to Sakho & Valencia
The recent success of Andy Carroll meant that Sam Allardyce chose him and Diafra Sakho up front, but it didn't really work, with neither really testing Wojciech Szczesny often enough.
Now, Hammers fans are calling for Enner Valencia to come back into the team in place of Carroll, and it's hard to disagree. The combination of pace and power from Sakho and Valencia helped the Hammers beat Liverpool and Manchester City at the start of the season, and going back to that front two is something Allardyce should consider.
West Ham aren't 'there'...yet
West Ham are gunning for European qualification after a superb season so far, but today showed that they still have a little way to go.
That's okay, though. West Ham were dreadful last season, finishing in 13th place with a dour brand of football. This year, they're playing more attractive football, and in truth they pushed Arsenal right until the last kick of the game. With a little bit more quality in the final third, West Ham could have got something out of the game - and that's something that Allardyce will look to rectify soon.
