Based on the league table and current form, the match between Union Berlin (W) (10th place) and Werder Bremen (W) (5th place) promises to be an open and high-scoring affair. Werder is having a strong season, but is currently not in top form. Union Berlin, in the bottom half of the table, also displays an attacking style, scoring in every match, but their defensive play leaves much to be desired (on average, the capital club concedes almost two goals per game).
The key factor in favor of an over-all total is the head-to-head record and the defensive problems of both teams. In their first-round match, Werder defeated Union 3-0 (Over 2.5 goals). The hosts are conceding an average of 1.9 goals per game (38 in 20 matches), while the visitors, despite their high position, have only four clean sheets this season. Both teams prefer to play attacking football, which is especially noticeable in matches against opponents in the lower half of the table.
Considering that Werder is fighting for a European spot and needs a win, while Union Berlin almost always scores at home (in 8 of 10 home matches), we can expect at least three goals. A bet on Over 2.5 goals seems more reliable than the outcome of the match, as the visitors are considered favorites, but the hosts are capable of surprising attackers.
