But it's also a must-win for Bremen if they don't want to get relegated. If they don't win against Paderborn they can already start to plan their trips to Sandhausen, Aue etc. For a long time, I was sure that they have good chances to beat Paderborn but the closer we get to the match, the bigger my doubts get. Although they have not lost the last three away games, their performance was all but convincing in these games. And now that they have lost their last game, I fear that they will be extremely insecure, especially when they are almost forced to win this game (next one will be against Bayern). And together with an already shaking defence that's a really bad combination.
Paderborn on the other hand seems to just enjoy the remaining matches. This phrase sounds weird but I think everybody at that club is/was just thankful for the season in the first league (remember they played in the third league 2 seasons ago) Nobody expects much from them so they can play without any pressure.
So the more I think about this game, the more indecisive I get. Right now I'd probably bet on a draw or BTTS.
