Ronaldo was the inspiration behind United's title success last term and collected another winners' medal at Wembley as the Red Devils edged out Chelsea in the Community Shield.
But the 22-year-old Portugal star is expecting much more meaningful silverware this term, with United needing to go a couple of steps further than their appearance in the Champions League semi-finals last term.
"Our team is stronger than it was last year," said Ronaldo.
"It is always difficult to win the Premier League but we have bought four great players so we don't just want to win the league, we want the Champions League as well."
