Sam Allardyce admits it has not been easy during his short stint at Upton Park as West Ham look to seal a return to the top-flight at the first attempt.
The former Blackburn manager was recruited as Avram Grant's replacement in June and tasked with securing promotion during his first season in charge.
Things have, so far at least, gone almost exactly to plan, and the Hammers sit second in the Npower Championship going into the international break.
But, says Allardyce, it has not all been plain sailing during his brief tenure as the east London club try to live up to their tag as title favourites
"It has been a difficult job," he told whufc.com.
"A change around through relegation and then to deliver immediately is a massive task, which is why what we are doing has been extremely good in terms of what the players have achieved in such a short period of time.
"We live with the expectation, and it is as big as I expected it to be. There is no room for slip-ups.
"We want to get promoted but we have a long way to go and we are taking nothing for granted. At any period of time we could hit a bad run and we will have to cope with that if it comes.
"We are going great. We are second in the league and I am not sure I expected us to be there this quickly. We have got there and we have to sustain it."
