Totally agree
Luiz has been no more than average this season and his on pitch discipline that was there last season seems to have gone awry. He was sometimes so far out of position he was in another postcode.
In my opinion, he had got too comfortable with his status and position in the team and maybe thought he was undroppable. This could be the boot up the backside needed to get him back to the Luiz of last season but it is totally down to him...no-one else....not even Cahill can be blamed for this one.
luiz is a talented footballer ....lets see if he has any gumption about him and work hard to prove to the staff and his team mates that he deserves a place back.
Those that say...he is a leader etc...he might be , but not a very good one. There is no way he should ever be captain of this team.... let him worry about his own game, nevermind worrying about others.
Also, this thing about 'the others players like him and he is a good laugh' etc etc...... I will just remind you...that Diego Costa was loved by all in the dressing room as far as we know .....and we all know what happened there
