David Luiz says Chelsea fans will only be patient with Frank Lampard for six months.
The 41-year-old knows all about the expectations at Stamford Bridge, having played 13 years for the club.
A transfer ban until 2020 could give Lampard some leeway as he eases into the job, but Luiz thinks those expectations will remain high among supporters.
"I think everyone understands the moment and everyone understands to be patient, but in the end everyone wants to win," centre-back Luiz said, according to Football London.
"They are going to be patient in the first six months and then in the last six months [of the season] they want us to win.
"It is going to be like that, we have to think about that and do the best to make them happy.
"If you don't think like that [about winning trophies], then you can't play for Chelsea. The ambition has to be high. Of course, you have many, many fantastic clubs.
"They [other clubs] are working with the managers more than three or four years and they have amazing squads. On the pitch it is up to us to have to show our jobs."
