Bilic revealed that the Premier League is growing increasingly impatient as even a coach of Mourinho’s calibre is under immense pressure after a few poor results.
“There is not really a big difference anymore between Turkey and England in terms of patience shown to managers,” Bilic told Turkish newspaper Fanatik.
“Take a look at Jose Mourinho you can love him or hate him but he he could be considered the best manager in the world on paper especially when you look at his record over the past decade.
“He guided Chelsea to the league title just last season but it means nothing anymore just look at the pressure he is under.”
Bilic also stated that he is under no illusion that if West Ham start to lose games that his position could be under threat.
“The same applies to me ok sure we have had the best start in seven years but if you lose two home games the mood changes,” he added.
Bilic took over at West Ham after a two-year stint at Istanbul giants Beşiktaş guiding the Black Eagles to the quarter-finals of the Europa League last season.
The Hammers take on Sunderland next at the Stadium of Light on 3 October in the Premier League looking for their fourth consecutive away win.
