Expect Freiburg to line up in their usual 4-4-2, a shape that's become their trademark under this management. It's compact, it's narrow, and it's designed to frustrate. They'll sit in a mid-block, let Bremen have the ball in harmless areas, then spring through the half-spaces with quick, direct runners. The double pivot will screen the back four, and the wide midfielders will tuck in to make the centre of the park a minefield. Bremen, on the other hand, are expected to stick with their 3-5-2, a system that gives them width through the wing-backs but leaves them vulnerable in the channels. That's a dangerous trade-off against a Freiburg side that loves to exploit exactly those gaps. The midfield dogfight will be key — if Freiburg's central pair can outwork Bremen's three, they'll control the tempo and starve the visitors of service. Bremen's wing-backs will push high, but that leaves space in behind for Freiburg's strikers to run into. Set pieces are another layer: Freiburg are set-piece kings, and with Vincenzo Grifo still pulling the strings, they'll fancy their chances from every dead ball. Bremen's back three will have their hands full.
