This culminated in a stunning performance that beat Croatia in the final.Roll time to the summer 2021, and Mbappe failed to pay the crucial penalty that saw France exit Euro 2020 in 16 defeats at the hands Switzerland.L'Equipe, a French newspaper, wrote in their headline: "Fallen so high."Mbappe will likely feel this is a small setback in his remarkable career. But is there any reason why he and his team-mates, the world champions, looked so out of sync and are now heading home?Mbappe in the midst of a nightmareMbappe entered the tournament after scoring 41 goals last season for club and country, winning the French Cup with Paris St-Germain.His Euros campaign was one to remember as he failed in any of the four matches. His 14 shots without scoring is the highest by any player up to this point.Yann Sommer saved the 22-year old from taking the fifth penalty against Switzerland.Eurosport.fr's player ratings suggested Mbappe was "in the midst of a disaster", while Chris Sutton stated on BBC Radio 5 Live that he had "fluffed in the biggest moment" and "didn't step up".Gary Neville, former England defender, said on ITV: "You just know as Mbappe was coming up. You thought, "Oh no!" He did have a few moments of extra time, but it didn't work out for him.He has high aspirations to be the best player in the world, like Lionel Messi and Cristiano Ronaldo. However, this is just a bump in his road. He will get through it.He is having a difficult time in this tournament, and it's a difficult one for him to handle as well as his French team."Mbappe was not able to impress the public watching the game - his score on BBC Sport's Player Rating was 4.44, which was higher than the 4.33 scored by Clement Lenglet (who was substituted at half time).Didier Deschamps, France's boss, said that Kylian Mbappe was extremely sad as all the players. However, nobody can be upset because he accepted the responsibility for taking the fifth penalty."There was no togetherness"France had only lost one of their 17 European Championship and World Cup games. That was the loss to Portugal in 2016.Their impressive form is evident in the fact that 12 of 15 BBC pundits predicted France would win the tournament.After the shock loss, Deschamps said, "It's my responsibility, and I told players that it was mine,"."When France wins, merit goes to the players. It is my responsibility to make things better. That's how sport works. Accept it, even if it hurts.Patrick Vieira, a former France midfielder, was harsh in his evaluation of the team. He said on ITV: "The greatest team deserve to be at the next round and tonight it is the Swiss.It was a poor French national football team. It was a team that didn't have any unity, no spirit. We didn't play together as a team, so we didn’t deserve to be in the next round."
