It's not hard to guess what the main topic at the next family lunch in the Mbappe household will be. In fact, we can try to paint the picture…After the usual catch-up over a nice meal, while the proud parents gaze at their two sons with tears in their eyes, happy to have the family together again, Kylian and Ethan will – as every child ever – get their chance to vent, and both will complain about the same thing – Real Betis!Parrott's plumage outshines Madrid's stars: Mou suffers first La Liga defeatWhy? Believe us, there are plenty of reasons…Last Friday, Real Madrid faced the Seville club in La Liga, and it didn't go well, to say the least.Los Blancos fell to a 1-0 defeat at Estadio de la Cartuja, thanks to Troy Parrott's winner, with Kylian Mbappe emerging as a tragic figure after missing a stoppage-time penalty to secure at least a point for his team. The whole stadium, as well as several Betis players, laughed in his face and taunted him.Mbappe Penalty Miss in Real Betis vs Real Madrid game. pic.twitter.com/jvc9CNSHZy— Daily Foot Vibes (@dailyfootvibes) September 4, 2026 However, little did he know that it was only the beginning of his family's struggles with Los Verdiblancos.Last night, in the Champions League, Ethan Mbappe faced Betis with Lille, and things couldn't have gone better until the break.The Ligue 1 side was 2-1 up, while the 19-year-old even assisted for Ayase Ueda's opener. Young Ethan looked set to "avenge" his brother, and nothing suggested that things were about to take a turn for the worse.Epitome of humility – Mbappe: "Who do I vote for to win Ballon d'Or? For myself!"And then, the Betis effect started.In the four-minute span – between the 49th and 53rd – the Spanish club completed the comeback through Marc Bartra (his first career brace) and Troy Parrott (again that guy!), taking the 3-2 lead.Just three minutes after the Irishman's goal, Ethan Mbappe committed a horrendous act, deliberately elbowing opposing defender Natan, and leaving the referee with no choice but to send him off.Ethan Mbappe’s red card 🔴 pic.twitter.com/iRH0lol1fa— The ANF Club ⚽️ (@adjorNfriends) September 8, 2026 With a man up, Betis comfortably maintained the lead, registering their first Champions League victory since November 1, 2005.Therefore, Ethan put the finishing touch on a miserable few days for Kylian and Ethan against Los Verdiblancos, who might just have earned themselves the "honor" of becoming the Mbappes' archenemies.But they won't care much, that's for sure.UEFA CHAMPIONS LEAGUEROUND 1TuesdayAEK – LASK 1-0 (1-0) /Marin 21/Club Brugge – Aston Villa 2-3 (1-3)/Vetlesen 19, Tresoldi 61 pen – McGinn 11, Buendia 22, Jackson 43/Porto – Manchester City 0-2 (0-0)/Haaland 47, 90+1/Dortmund – Villarreal 3-2 (0-0)/Veiga 53 og, Guirassy 80, 85 pen – Mourino 66, Guirassy 90+3 og/Lille – Betis 2-3 (2-1)/Ueda 12, Ribeiro 36 – Bartra 33,49, Parrott 53/Real Madrid – Inter 2-1 (2-0)/Mbappe 14, Valverde 23 – Augusto 77/Wednesday19.45: (1.08) Barcelona (13.0) Feyenoord (20.0) 19.45: (1.23) Stuttgart (6.75) Viking (11.0) 22.00: (1.75) Liverpool (3.90) Atl.Madrid (4.50) 22.00: (4.90) Napoli (3.60) Arsenal (1.75) 22.00: (1.05) PSG (14.0) Slovan B.
