Chelsea boss Thomas Tuchel remains hopeful of adding to his squad after victory at Everton.
Tuchel saw his team kickoff the season with a 1-0 win.
He later said: "If we can add, we add. We are open to everything and I think we can use new energy and new legs and fresh input to bring us to a new level.
"If not, we will push this team but I think we could use some more input and some more quality. We are on it.
"I don't want to put pressure on us but at the same time I don't want to lower our expectations."
