"Our first aim is to remain in the A division," said the former Dutch Under-20 Women's coach. "The easiest way is to win one game in the group so you can play for the first 12 positions."
For Great Britain, a top 12 finish in A Division is not out of the question for a side that only made their debut in the top flight last year. Under then-Head Coach Damian Jennings, the GB Under-20 women finished eighth overall, notching wins over Latvia and France.
A year removed from the 2011 campaign and with experienced players Ella Clark and Christina Gaskin forced to withdraw from the squad through injury, as well as a new man being at the helm since only May this year, expectations will be tempered.
Great Britain have a core of players returning for a second straight season of top flight basketball, experience that will prove vital as the team go up against difficult opposition in Group D opponents, Russia and Serbia as well as facing the Slovak Republic.
Erin McGarrachan and Renee Busch are two of the notable returnees and both have shone in recent pre-tournament preparation games with the pair top scoring in warm-up games.
Jennie Rodgers who completed a successful season with Loughborough University Riders joins the duo of McGarrachan and Busch in Hungary, having replaced the injured Gaskin.
Griffioen's team will need to pull together for tip-off today as they face a Russian side who have finished winners of the competition in four of the last eight years, before meeting with Serbia the following day.
Great Britain round off their Group D experience by playing Slovak Republic, in what could be a make-or-break game for GB.
"Nobody is expecting us to win, Russia are a very strong country," conceded Griffioen as he spoke about the opening clash against the 2011 runners-up.
"I think the most likely (game) to win should be the game against Slovakia, I think that's the key for us. Because one of our goals is to remain in the A Division and if you want to be sure to remain, you have to win one game in the group. Maybe we can surprise Serbia otherwise you have to beat Slovakia in the third game."
Griffioen is pleased with the Group D schedule his side have been handed in Debrecen, noting that by facing Slovakia in the final group game, he will have maximum time to plan for the game likely to be the best opportunity for a GB victory.
"I prefer to play Slovakia in the last game because then we can see how they play. I'm the type of coach who wants to prepare his team for the game."
Standard Life GB Under-20 Women play their first game of the European Championship against Russia today (16th August). Tip-off is at 7:30PM (UK time).
