The Portuguese winger believes they can manage it if they continue to work hard.
“All the guys have to continue playing like we know we can,” Ronaldo told Zoo magazine.
“We can’t relax. I know I don’t like to. I’ve a long road ahead of me and I want to be in this position, winning awards and trophies while I can.
“Every game is important because if we win, it improves our confidence. I’m at a club that guarantees trophies and that makes me happy. When we compete for a cup, we know we can win it.
“Last year we did the double of Premier League and Champions League and this year we have a chance to win five.
“We’re doing well in all competitions and it would be incredible if we could win them all. We have to continue working as we have been.”
