O’Shea believes Owen will soon start weighing in with goals, despite failing to score in United’s 1-0 win over Birmingham.
He said: “Michael was unlucky with a couple of chances but I’m sure he’ll get off the mark soon and, like Wayne, get his goals in runs.
“As for Wayne, I think pre-season was so important, for him to get that sharpness he needs.
“Once he’s sharp, he’s so hard to stop. His goal will give him confidence and that can only benefit us.”
