Kylian and Ethan Mbappé form a new Rouge et Bleu brotherhood

Against Metz last night, Ethan Mbappé made his competitive debut for Paris Saint-Germain’s first team. By joining his older brother, Kylian, on the pitch at the Parc des Princes, the Paris pair continued what is quite literally a family tradition at the capital club.

It's a custom that was started by the Dossevi brothers all the way back in the mid-'70s. The year is 1975, and with Othniel Dossevi (22 appearances, nine goals) leaving Paris Saint-Germain three years after arriving, his younger brother, Pierre-Antoine Dossevi (two appearances, one goal), is about to spend a season at the capital club. For the first time in Les Rouge et Bleu's history, two brothers from the same family would play for Paris's first team.

Two years later, the Brisson brothers found themselves plying their trade at Paris Saint-Germain – at the same time. François Brisson (87 appearances, seven goals), who represented the club from 1975 to 1981, was joined by his twin brother, Gilles Brisson (eight appearances, no goals), for the 1977–1978 season, and 45 years later, it's now the Mbappé brothers who have made their way into PSG's quite literal band of brothers, as Ethan earned his first few minutes of competitive game time alongside big sibling Kylian, who joined the capital club back in 2017 and has since become its all-time top scorer, netting 233 goals in 282 games.

Finally, that passion for Les Rouge et Bleu can also be passed down from father to son. This was notably the case in the Djorkaeff family, with Jean Djorkaeff (68 appearances, seven goals) representing Les Parisiens from 1970 to 1972 and, in the process, becoming Paris Saint-Germain's first-ever captain. 23 years later, his son, Youri Djorkaeff (47 appearances, 20 goals), would also go on to conquer the hearts of the Paris faithful by lifting the UEFA Cup Winners' Cup for the club at the end of a historic season.

In more recent times, Jérôme Alonzo prolonged this unusual phenomenon by making 101 appearances in goal for Paris between 2001 and 2008, succeeding his father and the club's former interim head coach, Pierre Alonzo, who enjoyed spells in charge of the first team in 1977, 1978 and 1979 before being part of Les Rouge et Bleu's coaching staff in the 2000–2001 season as an assistant manager.

With Ethan and Kylian now leading the way, Paris's family history still has plenty of life ahead of it.
