MANCHESTER UNITED fans have demanded that Wayne Rooney’s son Kai be “promoted to the first team immediately” after starring in an incredible TikTok video.

The 14-year-old is following in his father’s footsteps by starring for the Red Devils, albeit their youth side.

Kai has scored an amazing 56 goals during his first full season in United’s academy.

And if he enjoys half the success his father did, Kai is set for a bright future in the game.

But it’s not just the teen’s scoring prowess that has delighted fans.

A video on TikTok posted by @rhelitecoaching showed Kai being worked hard in a one-on-one training session.

The youngster showed off his various physical and technical skills while putting in plenty of hard work.

Kai’s determination and grit showed he is definitely on the path to emulating dad Wazza.

And supporters were delighted to see a Man United youngster putting in the hard graft.

The current first-team squad have failed to impress in recent weeks, with a string of poor results leaving them outside the European spots.

But fans feel Kai could teach Erik ten Hag’s men a thing or two about putting in more effort.

One said: “You can tell he has something special, we need to keep him and develop him right.”

Another added: “Future United first team star like his father. Let’s not put too much pressure on the lad though.”
