First-half goals from Patrick Schmidt and Jordan Williams gave the Reds a deserved win at the Riverside Stadium as they cast aside Saturday's loss in their Championship opener with Luton Town in the perfect fashion to earn a glamour trip to face Frank Lampard's Blues.
Struber said: "It is a bonus game and not more. Reading (on Saturday) is very important for everyone and then we have a focus and match plan against Chelsea.
"I am very happy for my team we can play at Chelsea, it is a very big chance to show what we can do.
"Sometimes, we need the right opponents to grow up and Chelsea are completely outstanding and on another level."
On his side's display, Struber, who handed starts to the likes of Brad Collins, Luke Thomas, Schmidt and new signing Michal Helik, added: "I think it was not brilliant, but it was good.
"Our performance was okay, especially in the first half when we played good on the ball and had control and good solutions and overloads.
"The set-up was very good and they could not calculate our game plan.
"We handled their aggression well and the second half was a set-piece and free-kick fight and my boys showed me we are ready against a good physical team.
"We deserved the win and now we have a good recovery for the next game.
"We created a match plan and it was a good feeling for me. We were surprised by the aggression of Luton, but we handled that better."
