Michael Schumacher’s kids share beautiful tribute to their dad on his 54th birthday

Michael Schumacher's kids have shared some old photos of their father to mark the Formula One legend's 54th birthday.

Schumacher retired in 2012 after a stellar career on the track, but just a year later he was involved in a life threatening accident while skiing on the slopes with his son Mick.

He suffered a life changing brain injury, which caused him to be in a medically induced coma.

He has not been seen or heard publicly ever since.

Mick, now 24, took to Instagram to pay tribute to his legend of a dad.

"Happy birthday to the best dad ever. Love you," he wrote, sharing two throwback shots of his dad from yesteryear.

One shows Schumacher doing what he loved: in the driver's seat of a race car.

The other shows the father and son smiling and posing inside a picture frame for the photograph.

Mick's sister, Gina-Maria, also shared an old happy snap of the pair.

She wrote: "Happy Birthday Dad. Throwback to our karting times."

She also called for her father to keep fighting, referencing his brain injury that saw the racing legend withdraw from public life.

Fans flooded the comments section of the Schumacher children's accounts, sending best wishes and love to them and their father.

One social media user said: "You, and your wonderful family, show so much strength and resolve. I'm full of admiration. Thinking of you all on your Dad's day, as I always do."

A second added: "Happy Birthday Michael! Keep on fighting, we're praying for you."

While a third commented: "Happy birthday to the BEST driver ever."

During his astonishing career, he won two titles with Benetton in 1994 and 1995, later winning five world championships in a row for Ferrari between 2000 and 2004.

He first retired in 2006 but was lured back into the sport by Mercedes in 2010 before calling time on his career again in 2012.

Mick is now making a name for himself in F1 with Haas and has previously said that he 'would give up everything' just to talk to his father about motor racing.

In July, Corinna, matriarch of the Schumacher family, broke down in tears whilst speaking about her husband’s condition, admitting that 'he’s different now'.

Corinna has previously spoken about the F1 legend’s condition.

She said: "I miss Michael every day. But it's not just me who misses him.

"It's the children, the family, his father, everyone around him. I mean, everybody misses Michael, but Michael is here."

She added: "Different, but he's here and that gives us strength, I find."
