Owen missed out on Fabio Capello’s squad for England’s game against the Holland on Wednesday.
“Michael has just arrived at the club, and his pre-season work has been very promising for us,” said the Red Devils boss.
“We are very, very pleased with him. He has not missed a training session, has shown a great attitude and good professionalism.
“His time will come because once he starts bedding in and getting regular football with us, which he will do, then that is the best way for him to get into the England squad.
“I did not expect Fabio to pick him on the back of what he did 10 years ago. What he does this season with us will be the deciding factor for him.
“I hope he does go to the World Cup because it would be a great tribute to him, and also more significantly, he would have done well for us.”
