It's saddening to see Real Madrid donating penalty kicks to charity by giving it to the Mbappe. At first, I defended him when he missed penalty against Liverpool and give him a benefit of doubt because even the great players like Ronaldo do miss penalty at times but missing two penalties in a row in important games is too bad. I can't defend the indefensible, you either know how to do it well or you stay away from it.
The problem with Mbappe I that he has lost his confidence. Mbappe used to be a player that believed so much in himself. He's the kind of play to bet on himself in any attacking scenario, but now he doesn't just have the dawg in him anymore. The Mbappe of PSG is very different from the one in Madrid.
At PSG he always wanted the ball and always running at defenders, in Madrid, he hardly even makes runs to receive the ball.
When a player has lost confidence, it affects all aspects of his game. They cant convert chances, they don't instil fear in opposing defenders so he's easier to deal with
Hopefully, he gets his confidence and form back because Madrid needs him. Since the midfield is not a midfield that can create loads of chances every match, the attack needs to make use of every chance they get.
