Dalla Valle put the finishing touches to Cherries' facile 3-0 victory over Oldham on Saturday, capping an eye-catching cameo with a stunning goal.
The Finnish teenager, signed on a month's loan from Fulham, netted with an emphatic left-foot strike just 11 minutes after coming off the bench.
His composed effort helped Cherries despatch the Latics with consummate ease as Bradbury's unbeatables' opened up a four-point gap in second place in League One.
Dalla Valle has been drafted in to bolster Cherries' striking options, the 19-year-old certainly giving Bradbury food for thought ahead of tomorrow's trip to Exeter.
Bradbury said: Lauri has come in with a big reputation for being a good goalscorer. It was said he was the best finisher to come out of the Liverpool Academy and things like that aren't said lightly.
He had one half-chance on his weaker foot and it was a great finish. He has got a good touch, he likes to run in behind and works very hard. He is another player we can rely on to compete in every game.
You need to stretch teams to give you space to play, especially away from home. Lauri and Danny Ings can both do that. As good as Danny has been, he needs a little rest every now and again to get the best out of him.
Dalla Valle, who bears a striking resemblance to countryman Mikael Forssell, the former Chelsea and Birmingham forward, made one brief substitute appearance for Liverpool in the Europa League before moving to Fulham in August.
He said: I was delighted to get the goal and it was a very good debut for me. We won the game and that was the most important thing.
I just want to get as many games under my belt as possible and try to score as many goals as I can.
I want to help the team. It will be up to the manager whether I start against Exeter.
This is the first time I have been on loan and I want to show people what I am capable of. Bournemouth are second in League One and, like me, they are ambitious to progress.
Before I came here, I didn't know too much about League One or Bournemouth so did some research on the Internet. I know some of the teams in this division like to play the long-ball game but Bournemouth are not one of them. That suits me because I like to play the way they like to play.
