Stuttgart vs. Mainz (Sunday, 2.30pm)
Stuttgart will be aiming to make it three wins in a row in the Bundesliga when they host Mainz 05 on Sunday.
Mainz, on the other hand, have failed to win any of their last 10 league matches.
We say: Stuttgart 2-1 Mainz 05
Despite struggling to pick up wins and score goals this season, Mainz have been defensively secure since Siewert took over in November, only conceding eight goals in his 11 league games in charge.
However, they will face the third highest goalscorers in the Bundesliga when they take on Stuttgart on Sunday, and we are struggling to envisage a scenario in which that run of conceding no more than one goal in a game under Siewert does not come to an end for the visitors.

Hoffenheim vs. FC Koln (Sunday, 4.30pm)
Hoffenheim will be aiming to end a winless run of six league games when they host FC Koln on Sunday.
The visitors, meanwhile, secured only their third win in the Bundesliga all season when defeating Eintracht Frankfurt last time out.
We say: Hoffenheim 1-1 FC Koln
As already mentioned, Hoffenheim tend to score and concede in almost every match they take part in, and we do not expect any different on Sunday.
The visitors should be confident after returning to winning ways last weekend, and they could move out of the bottom three with a victory here. However, we can envisage the two sides playing out a score draw.
