It all comes down to this. The three remaining places at the Final Four will be sealed on Tuesday and Wednesday as the playoffs reach a dramatic climax. Here's your quick guide to Game 5.
Game 5: The pinnacle of playoff basketball is here!
Panathinaikos AKTOR Athens vs. Maccabi Playtika Tel Aviv
A thrilling and high-scoring series will conclude as Panathinaikos welcomes Maccabi to Athens, with the momentum back on the Greens' side after Game 4's 88-95 thriller in Belgrade.
Panathinaikos backcourt duo of Kostas Sloukas and Kendrick Nunn will look to maintain the form that saw them combine for 47 points and 10 assists on Thursday, while Ergin Ataman's men will also feel confident about going inside the paint after Dinos Mitoglou and Mathias Lessort shared 30 points and 11 rebounds.
Maccabi's hopes took a blow when backcourt ace Wade Baldwin reinjured his hamstring and played just 7 minutes in Game 4. Baldwin is not expected to play in Game 5. That said, Tamir Blatt showed he can also be a factor after providing 13 points and 7 assists with no turnovers in the last game. Lorenzo Brown also has stepped up to score at least 16 points in each of the last four games.
Josh Nebo and Jasiel Rivero will try to crash the glass to earn extra possessions for Maccabi, which claimed 15 offensive boards last time out. But the Greens can also play hard, especially through Lessort, who has drawn an average of 9.8 fouls per game during this compelling series.
AS Monaco vs. Fenerbahce Beko Istanbul
After a defensive grind was edged by Monaco on Friday to make it a 2-2 series, Fenerbahce will look to recover its usual offensive fluidity as the series comes to a close in the principality.
Game 4's lowest-scoring result of the entire playoffs, 62-65, was very unlike the high-scoring shootouts that had preceded it, with nobody scoring more than Marko Guduric's 14 points or Elie Okobo's 13. Head coaches Sasa Obradovic and Saras Jasikevicius could well introduce some new wrinkles in the hope of gaining an edge.
The series has been lacking a big performance from Monaco star Mike James, who had averaged just 11.2 compared to his season average of 17.9, shooting just 23.8% from three-point range. This would be the perfect time for James to recover his usual standards, while Fener star Nigel Hayes-Davis will also look to bounce back after being held to 10 points in each of the last three games and converting just 28.6% of his long-range shots in the series.
The physical battle will clearly be crucial, so expect central roles for Monaco big man Donatas Motiejunas (12.5 points per game during this series) and the visitors' Georgios Papagiannis, who had a double-double of 10 points and 11 boards last time out.
FC Barcelona vs. Olympiacos Piraeus
The final ticket for the Final Four will be taken as Barcelona and Olympiacos go head to head to conclude a series which had been very tightly contested until Game 4, when the Reds handed out Barca's heaviest-ever road defeat to tie the series and seize the momentum.
That 92-58 Olympiacos victory saw a sparkling performance from Shaquielle McKissic with 21 points on 8-for-11 field goal shooting, while Nikola Milutinov dominated the paint to the tune of 11 rebounds in his first full performance since returning from injury.
Two more Olympiacos big men, Moustapha Fall and Filip Petrusev, also had a strong influence on Game 4, combining for 22 points and 10 boards. Barca will look for its own centers, Jan Vesely and Willy Hernangomez, to bounce back after the Spanish team was outrebounded 47-31 on Thursday.
Barca's only double-digit scorer last time out was Jabari Parker (10), and he has been in great form throughout the series with an average of 15.0 points on 62.5% three-point shooting. For Olympiacos, a big boost has been the return of veteran leader Kostas Papanikolaou, who made 3 of his 6 attempts from long-range in his comeback appearance in Game 4 as well as offering the positive energy that will be very much needed at Palau Blaugrana on Wednesday.
