Mikel Arteta says new signing Jo has settled quickly thanks to the spirit within the Everton camp.
"When a new player comes in, then he is made to feel part of the whole thing," explained Arteta.
"That's what happened with Jo. The lads made a fuss of him and made him realise what he was part of, and he responded.
"You can't get by on spirit alone, and we don't because there is great talent too.
"We are in the last eight of the cup and we feel we can go further. We really want to win it."
