Both teams have shown inconsistent results in this championship. Greece managed to win against Portugal with a score of 3-2, indicating a high level of competitiveness from their team. Meanwhile, Romania suffered a defeat against Portugal with a score of 0-3, demonstrating their unstable and unpredictable form. Additionally, Greece impressed with their unity and balanced play, which could be a key factor in this match. Despite Romania causing an upset by defeating Turkey, it is important to consider possible psychological aspects. After such a significant victory, the team may feel satisfied and have reduced motivation for the next match. Taking all these arguments into account, I believe that Greece has a better chance of winning in this matchup.
