Canada vs Republic of Ireland: What has been said?
Ireland manager Pauw: "I have said it many times. We will give our all and we will not be afraid. We will not hide because of a fear of failure because we don't have that.
"Something proves only to be impossible the moment it shows to be impossible, and that is our slogan.
"We get everything out of ourselves, we prepare the best we can. We have a fantastic programme to prepare ourselves and we give our all. We give the best that we have at that moment.
"But in that we need to be realistic. It's our first World Cup. We do not have as many players as others have, but we have a fantastic group with a heart for Ireland.
"That is immense. We stick together. We're a team. We work for each other and we give ourselves for each other, and that is our biggest strength."
