"It's probably been the hardest (period) of my West Ham career over the last eight months because we've had so much to deal with off the pitch", Noble said.
West Ham captain Mark Noble will be on the sidelines for the Premier League visit of Leicester on Saturday.
The Hammers, who finished seventh last season, are in eleventh spot at present and have failed to win any of their last four Premier League matches.
"Still, for me, it was a bad decision because we are taking about Claudio Ranieri who did everything very, very recently with them". The players were unhappy in the dressing room after the Bournemouth match and they know they have to do better.
According to reports in The Times on Tuesday, West Ham United are lining up a move for Arsenal striker Lucas Perez. Saturday's game doesn't change anything in terms of what we need for the summer.
"Qualifying for the quarter-final of the Champions League definitely will give them a big boost".
Whilst West Ham are safe from relegation, Bilic needs a strong end to the season to make sure that his job is secured for next season, but they take on a resurgent Leicester City side.
"Unfortunately, now, nobody can say it's the wrong decision because at least these three results are brilliant for them and they look different".
The Ghana man's stop-start first season in east London has started to fire with goals in successive away games and the boss expects more to come as the Hammers aim for a top-half finish.
