Kylian Mbappe gatecrashes brother Ethan's post-match interview after PSG wonderkid makes his debut

Kylian Mbappe hilariously gatecrashed his younger brother Ethan's television interview after the latter made his senior debut for PSG in Ligue 1.

Luis Enrique's side saw off FC Metz 3-1 thanks at the Parc des Princes, with Kylian's younger brother introduced as a second-half substitute during the final stages.

Having already found the net twice, PSG's No.7 decided to intervene on Ethan's post-match chat with club media afterward, making for a wholesome interaction between the pair.

Fellow PSG defender Presnel Kimpembe took on the role as interviewer as he first asked the teenager just what he made of his maiden bow for the Parisians.

"It’s always nice, I started at the Parc des Princes, in front of our supporters, so I am very happy," Mbappe Jr began.

"I hope there will be more matches. It is a great birthday gift for him, I’m very happy for him and for me too."

It was also a special occasion for older brother Kylian, as he celebrated his 25th birthday in style by netting twice for the reigning Ligue 1 champions.

Admitting he was happy to see his brother shine, he also noted how special an occasion it was to share the pitch with his sibling.

"I’m happy he loves it, but I love it even more," added the PSG forward.

"As a big brother, this is extremely pleasing. I didn’t think I was going to experience a special day like this. But this match, I will keep it in my memory."

Having both began their careers with AS Bondy, older brother Kylian enjoyed time with AS Monaco before completing his big-money move to the French capital back in 2017, where his stock has continued to rise in the years that have followed.

Although his younger brother is still just 16, he has also been at the club ever since his elder sibling arrived some six years ago and will have likely been watching his development closely.
