Tottenham boss Antonio Conte says there are a "lot of jobs to do" at the club after they were beaten by Chelsea in the Carabao Cup semi-final first leg.
Spurs lost 2-0 at Stamford Bridge thanks to Kai Havertz's early effort and a Ben Davies own goal but were outplayed by Conte's former club.
The Italian says the performance showed how far Tottenham are behind their London rivals.
"It is important for patience, for me also to have patience," said Conte.
The Spurs boss added: "There is a lot of jobs to do, in this moment, it is very difficult to understand which part you take to improve because there is a lot of situations to improve.
