The club's high-profile signing Rasmus Hojlund will have to wait to make his Old Trafford debut after being ruled out of the team's opening Premier League match, manager Erik Ten Hag said on Friday.

The 20-year-old Danish striker, bought from Atlanta for a whopping 72 million pounds ($91.33 million), is suffering from a back stress fracture.

He had a slight difficulty, as we previously indicated, and is not yet at the same level as our guys, so we must teach him. Before Monday's home match against Wolverhampton Wanderers, ten Hag spoke to the media. 

"It's always tough to predict a prognosis. We are certain and hopeful.  

Despite being linked with Harry Kane, who seems poised to join Bundesliga heavyweight Bayern Munich, United boss Jose Mourinho stated he was pleased with the purchase of Hojlund.

First off, we've chosen a striker, and we couldn't be happier with it, the Dutchman said. Kane is a fantastic striker. Without a doubt, it's a miss for the Premier League.

Despite a reported agreement with West Ham United for the out-of-favor defender, Harry Maguire is expected to be ready for United's Premier League opener.

Manchester United struggling with injuries 

Ten Hag said, "Of course (Maguire) is available," when asked about his availability.

It will take some time for Tyrell Malacia, as well as Amad Diallo and Kobbie Mainoo, because they are impact injuries, while all of the others, like Dean Henderson and Rasmus Hojlund, will need a few weeks because they are all short-notice injuries."
