Union Berlin has declined a lot lately; the capital club dropped to ninth place, six points behind the European competition zone. Union Berlin has become much worse in defense, conceding in 12 matches in a row.
Koln has been successful this season, sitting in seventh place, four points behind the European competition zone. However, the problems in the team's defense have not gone away–40 goals conceded (the worst results among the teams from the first half of the league table).
Both teams need points to get into the top 6, so Union and Koln will have enough motivation to attack. And defensive problems suggest goals must come from both sides.
Our prediction: both teams to score. We recommend the “BTTS - Yes” bet, odds 1.81
