There had been concern over the fitness of Teemu Pukki due to an ankle problem, but the striker was involved in his side's 1-0 loss to Estonia on June 4.
Pukki, who is the leading goalscorer in the squad with 30, is expected to lead the line for Finland, and he could be joined in the final third of the field by Union Berlin's Joel Pohjanpalo.
Rasmus Schuller and Fredrik Jensen are potential options in midfield and attack, but Glen Kamara and Robin Lod should get the nod, while Jukka Raitala and Jere Uronen should feature in the wing-back areas.
There is plenty of experience in the Finland squad, but there is expected to be a start at the back for Daniel O'Shaughnessy, who could win just his 12th international cap against Denmark.
A lot of the goalscoring burden is likely to fall on Pukki, who netted 26 times for Norwich City during the 2020-21 campaign, but there is enough talent elsewhere to allow the national side to compete in Group B.
Finland possible starting lineup: Hradecky; Arajuuri, Toivio, O'Shaughnessy; Raitala, Kamara, Sparv, Lod, Uronen; Pohjanpalo, Pukki
