Chelsea boss Antonio Conte fears a slow market could wreck their title plans.
Conte admits that a lack of new signings could have an impact on Chelsea's title ambitions this season.
He said: “It's very difficult to answer that question. I'm working with these players. I have been for only 40 days. We know that we can improve a lot with work.
“But, also, that it's important to have the right number of players in the squad to face the other teams. For the ambition now, it's very difficult to tell.
“We know Chelsea are a great team. Every team must fight until the end for the title. But, also, we know that last season the players were not fifth, or sixth, but tenth. Don't forget this."
