Bayern Munich vs Werder Bremen prediction

Bayern want to start the campaign on the right leg especially considering the match is played at home. They play against a traditionally weaker side today and Werder seem to be in poor form loosing games even to teams from lower divisions. The normal outcome here would be a classic home victory but I suspect the Ancelotti effect will push the score further and 4:0 sounds just about right especially considering Werder strikers are injured or sold during the transfer window. Bartels alone can hardly manage a goal by himself against a defence line like that.
