Schurrle left Bayer Leverkusen to join the Blues last summer in an £18m deal after impressing for club and country in a wide left role.
He told reporters at a pre-match press conference: "He needs some time to adapt to a different league, a different profile of competition.
"But he is a good player, an open kid who wants to work and to learn, so our hopes are on him. We are happy with the investment in such a young player."
The 22-year-old missed Chelsea's 4-1 win over Cardiff City last weekend with a leg muscle injury, but is back in contention for tonight's Champions League clash with Schalke 04 after travelling to Gelsenkirchen.
