The Nottingham Forest boss will take plenty of positives away from the 4-1 League Cup win at Adams Park which takes the Reds into the 3rd Round of the competition.
These will include goals for new signing Ishmael Miller and Robbie Findley with McGugan and Majewski also on target.
McClaren made clear his intention to win the game by naming a strong side and will now look for his men to take the winning habit into Saturday's big league clash against West Ham United.
He said afterwards: "Lewis and Raddy (Majewski) can certainly play and when they've got space to play and they've got runners like Miller and Robbie Findley going in behind, it's a big asset.
"They were at the heart of some of our best moves and they also both their reward in getting on the scoresheet themselves."
