Osman admits he's seeing Cahill's image everywhere as Everton do preseason Down Under.
He told evertonTV: "You can't turn the telly over without seeing his ugly mug on it, it's tough to do that then see him on the bus! I've got Tim Cahill overload!
Before adding more seriously: "It's great for Tim and it's great for us to have such a high profile player.
"I would have thought it is fantastic for him - we are not only in his home country but his home town as well. Hopefully he will enjoy the fact that his team is over here."
