Ireland manager Stephen Kenny: “You can’t go to Portugal and defend for 90 minutes and I think we have to go and be positive in our approach.
“Definitely it’s a challenge, there’s no doubt but we’re really looking forward to the week. It’s a great game for the players to play in.
"It’s a real tough challenge, Portugal have some really outstanding players, there’s no doubt about that, but a lot of our players are looking forward to showing what they’ve got.”
Ireland captain Seamus Coleman: “It’s not a case of ruining any parties or anything like that, because we have to focus on ourselves.
“Everyone in the world knows how important and how amazing Cristiano Ronaldo has been in the last 15 years. It’s incredible really.
“As a group we have to focus on what our plan is tomorrow and how we can stop them from playing. But they have a few players that we have to keep an eye on."
