West Brom boss Roy Hodgson admits the patience shown to Sir Alex Ferguson when he became Manchester United manager no longer exists in football.
Ferguson was into his fourth season at Old Trafford before winning his first trophy in a reign which has so far spanned 26 seasons.
In contrast, Albion's win over Chelsea on Saturday ended Andre Villas-Boas' spell at Stamford Bridge after just eight months.
Hodgson, who was sacked as Liverpool manager after six months, said: "Sir Alex has won so many since he probably thinks the first three and a half years were the warm-up.
"Will you ever get that patience back Sir Alex enjoyed? No. You won't because football has grown. Things move on.
"You have to be very careful if you have been in football a long time that you don't become the type of dinosaur that hankers for what happened in the past. You have to live in the present always.
"The way things are today is the way they are and if you are to carry on in the job, you have to carry on as it is today with mass media pressure which has heightened, not least of all because football is wall to wall and 24-7 in every respect.
"In some ways we should be grateful because it has lifted us up to a status we never had in the past. In terms of earnings, the people in football today are much luckier.
"Some people say it is good or bad but that's the way it is and we have to get on with it."
Albion's 5-1 win at Wolves three weeks ago also spelt the end of Mick McCarthy's reign.
But Hodgson said: "You can't feel any guilt. It would never occur to me if I lost my job to blame it on the last result or the manager of the team who inflicted the last result.
"I live in the present and know what the world is. With Mick going, I was very disappointed for him I regard him as a friend.
"I was saddened that situation came about and made my feelings to him but he didn't think for one minute it was my fault.
"It would be foolish of me to think that way as well because one day I'm going to lose a job and someone will be the victor which causes the axe to fall on my head."
