Slaven Bilic will be on familiar territory when West Ham attempt to put Wednesday's crowd trouble behind them.
The Hammers on Sunday head to Everton, where boss Bilic played for two seasons after leaving Upton Park in 1997.
The contrast between the old-school charm of Goodison Park and the vast open spaces at West Ham's new London Stadium could not be greater, even if the violent scenes at the EFL Cup game against Chelsea were an unwelcome throwback to the 1980s.
Bilic admits he remains a fan of Everton's tight ground - and not just because West Ham clinched a dramatic 3-2 win there last season.
