On his birthday, Manchester United wonderkid Kobbie Mainoo shared a cute photo from his youth.

Today Mainoo turned 19, and to celebrate, he posted several photos to Instagram.

Having a blast with family and friends on his 19th birthday, Kobbie Mainoo is seen here with his mom.

A photo of Kobbie Mainoo from his childhood, wearing a Manchester United AIG jersey, was uploaded online.

To commemorate his nineteenth year on our planet, Mainoo posted a handful of photos to his Instagram account.

Mainoo got a tattoo in one of the photos.

Brother and ex-Love Island star Jordan Mainoo-Hames also photographed with Mainoo.

The midfielder was spotted in a parking park wearing a blue jacket with cream sleeves and black and white stripe trim in the first photo of the collection.

The second picture showed Mainoo working out with Manchester United while wearing a wool hat, which, considering Paul Scholes’s previous comments on the matter, would irritate him.

Mainoo was seen in the third shot alongside his brother, Love Island star Jordan Mainoo-Hames, and rapper Rudz.

The following photo showed Mainoo and his teammate Diogo Dalot enjoying themselves at Old Trafford.

Then Mainoo proved he’s always had a calm demeanor by sharing a cute photo from his youth.

It was Mainoo’s Nike-produced AIG Manchester United kit that stole the show, though, as he sat back on a sun lounger with his hands behind his head and sunglasses on.

During the years 2006–2010, AIG sponsored Manchester United’s equipment.

Mainoo got a tattoo in the next shot, and in the last one, he was seen at a car park sporting a vibrant yellow jacket and black pants.

He wrote: “+1, Appreciate the messages 🏾” as the caption of his post.

Many of Mainoo’s teammates sent emotional remarks or answered with heart emojis.

“Goodbye, my little kobbs,” Amad Diallo said.

“Happy birthday, Mybro!” remarked Dan Gore, a fellow Carrington prospect.

“Happy Birthday, Kobe!” Manchester United’s attacking coach Benni McCarthy tweeted.

According to big brother Jordan, “My broyeee 🤍 love u man.”

A supporter commented, “Bro is so clean at everything he does.” in response to the post.

“Young champion, bless you,” another one yelled.

Another person asked, “Why is everything he does so clean?”

On Sunday, Mainoo will be celebrating his birthday at Wembley Stadium, where Manchester United will play Coventry in the FA Cup semi-final.
