West Ham defender Angelo Ogbonna believes Wednesday's EFL Cup clash with Chelsea will come down to a battle of the brains with Diego Costa.
Costa netted the winner as Chelsea fought from a goal down to beat West Ham 2-1 at Stamford Bridge in their opening fixture of the Premier League season.
But Ogbonna, who was managed by Chelsea boss Antonio Conte at Juventus, is determined not to see the Spain striker celebrating again in midweek.
'We know Costa,' defender Ogbonna, who played under Conte at Juventus, told the Mirror.
