His future at Upton Park may be uncertain but West Ham manager Sam Allardyce has insisted it's not affecting the players.

In the final home game of the 2014/15 campaign the Hammers are in for a mid-table slog against Everton on Saturday (May 16).

In addition to Big Sam’s future hanging in the balance both West Ham and visitors Everton have the chance to play European football next season via the Fair Play League conducted by governing body UEFA.

The former Blackburn Rovers chief said the main factor in the east Londoners' slide down the table was the lack of goals – something that has come back to haunt them from last season.

Allardyce said: “Our results have been about the lack of some core players on our team on a regular basis.

"We’ve managed to overcome the injuries to James Tomkins and Winston Reid, defensively we’ve been very sound.

“In recent weeks the lack of goals has been the big factor. We had 29 attempts against Burnley and didn’t score after the penalty.

"It just highlights our problem at the moment. It’s been a major downfall for us over the past seven games.”

Since arriving in 2012 Allardyce’s future has frequently been in doubt – never more so than in 2015.

With his 12 month rolling contract coming to an end in June the former Bolton Wanderers boss remains unflappable.

“When Bolton got promoted to the Premier League I signed a contract on May 29 when the season had finished,” said Allardyce.

“it was a good two weeks after the season had finished before we negotiated.

"It falls in the same lines as this season. We’ll sit down and negotiate and the outcome will be made clear to everybody when those negotiations are finished.”

“Of course the speculation will be flying all over the place because there are a lot of columns in newspapers to fill today.

"There’s going to be whisper here and whisper there and people getting third hand information from somewhere and it gets written about. It’s the world we live in today.

"Wherever I’m staying or going hasn’t been decided yet.”

The E13 side will have a welcome boost ahead of the match against the Toffees – with Winston Reid returning to the squad after a hamstring injury.
