Erling Haaland posted a photo of himself on social media that shows him using a breathing apparatus.

Haaland’s injury recovery recently took a blow when Manchester City’s medical staff pulled the striker from practice this week. He is a Norwegian.

The 23-year-old is having difficulty recovering from a foot injury that prevented him from walking during the team’s loss to Aston Villa last month, but he appears to be making every effort to speed up his healing.

The Norwegian striker appeared to confirm what Haaland had previously said—that he tapes his mouth shut when he sleeps—by posting the image on social media.

The Man City star posted a selfie on his Instagram story on Friday night, showing off his naked chest and the breathing apparatus covering his mouth.

“Think outside the box” was his caption for the photo.

Haaland said back in August that he covers his mouth with tape before going to bed and that he spends three hours wearing blue light-blocking spectacles before bed.

During his appearance on Logan Paul’s Impaulsive podcast, the 23-year-old revealed some of the secrets to his success.

“Sleep is the most important thing in the world,” Haaland declared.

Therefore, to get a decent night’s sleep, do simple things like filter out all the signals in the bedroom with blue-blocking glasses.

“It is not beneficial to do a lot of things; however, it is beneficial to do small things every day for a longer period of time.”

He has discussed in the documentary Haaland: The Big Decision how his liver and heart diet has contributed to his success.

He declared, “I am concerned with taking care of my body, even though you (other people) don’t eat this,” while displaying enormous slices of liver and heart from his butcher.

“I believe the most important thing is to eat good food that is as close to home as possible.”

Haaland disclosed that he only consumes water that has passed through an intricate filter.

“I get some sunlight in my eyes first thing in the morning because it’s good for circadian rhythm,” he stated. Additionally, I’ve started to somewhat filter my water. I believe my body can benefit much from it.

He consumes 6,000 calories each day in order to maintain optimum physical condition. He shared his “magic potion” last season on Instagram, which was a mixture of milk, spinach, and kale.

After defeating Everton in May of last year, he flaunted a platter of beef liver on Instagram.
