QUOTES
Republic of Ireland Manager Vera Pauw
"Finland are a completely different team to Sweden, who we played last week, but there are some similarities. They are very strong, they are very much a Scandinavian team, so they have very fit players, very strong players, they play very direct and have a lot of pace.
"We know that we have do more in possession and to create chances. Everybody would have seen that we tried to do that against Sweden but they were a very strong opponent. In this game against Finland we might have more opportunities to use possession and to do more with it.
"This game against Finland is the game where we really have to show what we've learnt over the last half year. We are excited about the challenge, this is what elite international football is all about and we feel that we are ready for it."
