Cahill has been Down Under for the last week during the latest stage of rehabilitation following surgery on his foot.

The Australia international midfielder had not been expected to be fit for the start of the season, but the strides he has made in the last fortnight have led to a more optimistic prognosis - and the opportunity for him to join the squad in the United States in order to step up his training programme.

Everton assistant boss Steve Round explained: "He is running now and everything seems to be going on the right track, touch wood, so we are looking to have him fit ready for the season."

Cahill underwent surgery at the end of the season to solve a recurring a metatarsal problem.

Injury restricted him to 28 appearances last season, netting an impressive 10 goals.
