|Hedo Türkoglu and Turkey must beat Spain and hope Poland lose to Great Britain in order to advance to Vilnius|
Spain and Lithuania are guaranteed a first and second place finish respectively.
For Poland it's enough to beat Great Britain in order to advance as third.
For Turkey to go through they need to beat Spain and hope that Poland lose.
Great Britain have an outside chance of qualifying but they need to beat Poland by a margin of 55 points or more and hope that Turkey also lose.
If Turkey lose against Spain and Great Britain beat Poland by less than the needed margin then Turkey advance.
In a possible three-way tie between Lithuania, Poland and Turkey, Poland go through as third.
Great Britain v Poland - Monday at 15:15 (14:15 CET)

Dardan Berisha's winning jumper has left the Poles needing just a victory over Great Britain on Monday to join Spain and Lithuania in the next round in Vilnius.
If the Poles were to finish level on points with Turkey, it would be the former who would go through courtesy of their head-to-head record.
"We knew how important this game was for us," said Berisha of Sunday's win.
"Now we need one more win to advance and we will go out with the same determination against Great Britain."
Team GB also have an outside chance.
Chris Finch's men must beat Poland by 55 points and hope Turkey lose to Spain.
After three straight losses, Great Britain finally tasted victory with an 85-73 defeat of Portugal on Sunday.
If they are to be successful, Poland will have to limit GB star Luol Deng, which is something Portugal failed to do and it cost them dearly.
Deng had 31 points to go with his 10 rebounds.

Turkey must win against Spain and hope Poland fall to Great Britain on Monday in order to progress to the Second Round of the EuroBasket.
Should Turkey and Poland both lose, then a goal differential tie-breaker would be used taking into consideration the games between the Turks, Poles and Great Britain to determine the third and final team to advance from Group A.
Orhun Ene's men lost 84-83 to Poland on Sunday to see their hopes of advancing in the tournament hang in the balance.
That defeat was their second in the competition following their 75-68 loss to Lithuania.

Portugal v Lithuania - Monday at 21:00 (20:00 CET)
Winless Portugal could not have asked for a more difficult game to end their EuroBasket adventure than against tournament hosts Lithuania on Monday.
The Portuguese go into the contest having lost all four games in Panevezys while Lithuania, despite their 91-79 setback to Spain, have clinched second spot in Group A.
"They are the most dangerous team in the group so it's going to be a very difficult game for us," said Portugal's Carlos Andrade, who had 24 points in his team's 85-73 loss to Great Britain on Sunday.
"But we will battle until the end, something we have done throughout this tournament."
