For a manager supposedly on the brink of the bullet every other week, Antonio Conte has won some very significant matches. Tottenham and Atletico Madrid away, now Manchester United at home. He's not keeping pace with Manchester City, of course, but he is hardly alone there.
Quite why he would wish to pick such an open fight with David Luiz, however, is a mystery. Surely he needs allies in a volatile environment?
Conte fell out with Diego Costa, too, but we understood. Costa was high maintenance and prone to sulking.
