The highly-rated Fulham striker yesterday boosted Lee Bradbury's frontline by signing an initial one-month loan deal with the League One high-fliers.
Dalla Valle is set to go straight into the Cherries squad for today's home clash against Oldham Athletic (3pm).
Likened to Fernando Torres by ex-Cherries striker and football pundit Steve Claridge, the Finnish teenager arrives with a promising reputation, having previously spent two-and-a-half years with Premier League giants Liverpool.
And after dropping into the third tier for a taste of first team action, the 19-year-old set his sights on helping Cherries cement their place in the top two.
When asked by the Echo what supporters could expect to see from him, Dalla Valle said: I am a striker and I am quite clinical in front of goal. I work hard for the team and do my best in every game.
I am here to do my best and to show people I am capable of playing in competitive games at senior level. Hopefully, by doing my best here it will be good for the club as well, and I can get goals for the club.
They are talking a lot about wanting to get promoted and do well so, hopefully, we will continue that.
I am delighted to be here and it seems like a really nice place.
Dalla Valle's deal runs until April 2, meaning he will be available for the League One matches against Oldham, Exeter, Southampton, Carlisle, Charlton and Peterborough.
Boss Bradbury was pleased to bolster his resources after previously missing out on loan deals for Middlesbrough frontman Jonathan Franks and West Bromwich Albion striker Simon Cox.
The Cherries chief received a series of positive reports when doing his research on Dalla Valle.
And he is hopeful the youngster will prove to be a good asset for promotion-chasing Cherries.
Bradbury said: He has limited chances to play (at Fulham) and where better to come and play at the start of his career than at a League One club that is going places.
Hopefully, he can fulfil his potential with us and give us a little push for the final bit of the season.
We spoke to people at Liverpool and Fulham and people that have trained and coached him. Not one person had a bad word to say about him.
All he needs is a chance and what a great chance it is for him to prove his worth to his parent club by coming down and doing well.
