Neymar Jr, and Lionel Messi were playing in PSG at the same time as Mbappe and they never won the Champions League trophy with the club. Why would Mbappe be the one to regret? Mbappe is a young player with a long successful career ahead of him. Right now he’s playing in one of the greatest teams in the world, Real Madrid will ensure his long term success in football.
Mbappe should never feel bad for now winning anything at PSG when he was playing with the likes of Messi and Neymar in the same team, it is just natural that it was never meant for them at that time to win the trophy because they lack adaptability to each others way of football. During that time, both Neymar and Messi are already a winner of the champions league trophy and won’t pay much attention to it as Mbappe will and if there is no collective efforts by all players then can’t achieve anything in the end. Mbappe is playing in one of the greatest teams in the world and he’s still very brave and has all it takes to win the champions league trophy. So he won’t feel bad or regret, he will one day win the champions league trophy in my opinion.
