as I said above, Ivan Juric will have a huge effort, he has to respect a standard that Gasperini has imposed which is certainly a high standard, he also won a Europa League which is no small feat for Atalanta, so expectations are high, in my opinion he will be sacked in a short time
Handling a team that has been with one coach for a long time is not easy because Ivan Juric certainly has a different view or philosophy from Gesperini to implement tactics so it takes time for Ivan Juric to adapt to make the Atalanta team according to his wishes.
I think if Atalanta management expects instant change then it will not happen and if too much pressure with targets then it is likely that Ivan Juric will not be Atalanta's coach for long.
