Pierre-Emerick Aubameyang showed no leadership against Brighton
One thing a captain should never do is have a go at a young inexperienced player in front of millions. That is exactly what Auba did and it was wrong.
A captain leads by example, a captain lifts the players, a captain leads from the front, a captain inspires.
What a captain does not do is call out one of the youngest players in the team. he does not go AWOL when the team needs him to lift spirits. He does not take his time going for toilet breaks in the middle of the game.
Of course, if a player needs the toilet he has to go but the way he walked back on was just far too casual.
And of course, a captain does not have a relationship with a person that attacks his teammates on social media.
Aubameyang did everything wrong as a captain last night and is not fit for the role.
Who should replace him? Personally, I would give the role to Bernd Leno. He is the only player in consistently good form and carries no baggage with him. You do not stick with a poor leader because you do not have a ready-made replacement.
If a player, any player, is incapable of leadership then he must be removed, that player becomes a liability under those circumstances.
This is not a criticism of Auba as a player, only as a leader.
