It doesn't matter what you do, where you work or how much you are paid, whenever a new manager is appointed you should expect some big changes.
And Antonio Conte is no different.
Pep Guardiola was the first new name to ban junk food from his players' diets to get them into shape during pre-season and the Chelsea manager has decided to follow suit.
Conte is well regarded as a stern disciplinarian and Chelsea's stars are set for somewhat of a surprise when they return to the club's training ground for the first time since their pre-season tour on Thursday.
According to The Times, fizzy drinks and sauces have disappeared from the staff canteen as the Italian boss cracks the whip on anything that could affect the players' performances on matchday.
The Blues' players have been treated to pizzas after matches in the past but Conte has already eradicated that tradition to add to the list of banned foods.
You would assume that players are educated to avoid consuming anything that could have a detrimental effect on how they play, however, Conte does not want to take any chances with the likes of Tomato Ketchup.
Conte has also made a big change regarding their pre-match meals. The previous preference for carbohydrates just hours before kick-off has been scrapped for proteins to avoid the possibility of feeling bloated later on in the day.
Last year, Diego Costa was among those to start the season looking unfit and overweight, which no doubt played some part in the team's poor form and Jose Mourinho's eventual sacking.
There is no danger of that this time around, though, Conte has inflicted plenty of fitness work on his squad, with double and even triple training sessions regularly being used since the former Juventus boss began his tenure.
Chelsea's first game of the new Premier League season is against West Ham in a London derby on Monday night.
