West Ham assistant Mervyn Day has admitted he is unsure over his and manager Alan Curbishley's Upton Park futures.
Curbishley has guided the Hammers to a mid-table finish this season despite being without several key players due to injury.
The former Charlton Athletic boss kept the club in the Premier League on the final day of last season, but Day has conceded their futures at the club are far from secure.
Speaking ahead of Sunday's season-ending clash with Aston Villa, he said: "Who knows, you can't help speculation.
"Everybody in football, you speak to any manager or coach, and they acknowledge what a decent job we've done so far in the circumstances.
"Whether people in our position think that speculation has got some foundation or whether it's justified is another matter."
Meanwhile, Day has challenged the Hammers to bounce back from last weekend's 4-1 thrashing at Manchester United and secure a 10th placed finish in the table by taking three points off Villa.
"For personal pride, it doesn't matter if it's Spurs or Newcastle, we want to finish in the top 10," he added.
"That's been the goal ever since the start of the season. We wanted to be in the top half of the table.
"If we achieve that, given the amount of injuries we've had, I think we'll have done reasonably well."
