"We're really excited about playing Champions League football," said Marley. "And we're definitely in the right frame of mind for this tournament.
"We are going into it full of confidence, and if we hit our peak it will take a very good side to beat us."
Most of Everton's players were in action for England last week, either for Hope Powell's senior team or the Under-19's - also coached by Marley.
The four young Toffees in Marley's national squad emerged triumphant from the European Under-19 Championships, as England won the title for the first time.
It's amazing to be associated with the competition

Meanwhile , eight Everton players were in the senior squad that beat Denmark 1-0 in their last match before next month's European Championship finals.
"We couldn't be better prepared," said Marley. "The girls have enjoyed playing and winning for England, and we'll aim to carry that on for Everton."
Everton and Arsenal have a massive Champions League incentive as the final, like the men's, is set to be played at Real Madrid's Bernabeu Stadium next May.
Marley said: "For the women's game to be given the recognition of a Champions League competition, with the final at the same venue as the men's, is inspirational.
"It's amazing to be associated with the competition, and the possibility of playing at the Bernabeu will be a big driving force for us."
