While Crystal Palace head to Merseyside on a high after their last-gasp triumph at Sunderland, Ronald Koeman is looking for an immediate response from his Everton players following a wretched performance at Bournemouth.
Koeman is concerned about the time it is taking for some of his squad to take on board the high intensity pressing game he favours and believes they have a mental block about it.
'Sometimes it's difficult because our strikers are not used to press how we tried to press the opponent and it takes time,' said Koeman, who has 'no idea' if Ross Barkley has done enough to warrant an England recall.
