Everton boss Moyes welcomes Naismith signing
Naismith completed his switch on Wednesday.
"It is good if you can get your boys in at pre-season and get them involved," said Moyes.
"It gives everyone a lift. That's why we've got a full room today because everyone very rarely sees Everton signing players at this early stage.
"But I hope it's not the last and I'm hoping to get some more business done, certainly before the season gets started."
