Celtic’s team sheet in Germany has raised a few eyebrows. With Martin O’Neill giving a number of players a rare chance to start a game in Europe.

Viljami Sinisalo starts in goal. In front of him, Colby Donovan, Dane Murray and Marcelo Saracchi come into the back line. Reo Hatate and Luke McCowan are in midfield, with Daizen Maeda, Yang Hyun-jun and Junior Adamu leading the attack.

It is a bold decision with the tie sitting at 4-1 to Stuttgart. Turning that around away from home against a side who were comfortable at Celtic Park last week feels unlikely. Still, European nights have produced bigger swings over the years. An early goal changes mood. A strong first half builds belief.

There is also Sunday to think about. The Glasgow Derby waits. O’Neill has clearly weighed the risk. Fresh legs tonight could mean sharper legs at the weekend.

For some of these players, this is rare ground. Donovan and Murray have not started many games of this level. Sinisalo has to command his box against a team that crosses early and shoots from range. Saracchi will be asked to time his runs, knowing Stuttgart look to break into the space full-backs leave.

Hatate’s role feels central. If Celtic are to have any rhythm, he must take the ball under pressure and move it quickly. McCowan will need to match the tempo and close gaps when Stuttgart counter.

Up front, Maeda’s running gives an outlet. Yang has to be brave one-v-one. Adamu needs to hold the ball when it sticks.

It is a night that could reshape O’Neill’s thinking. A strong display from any of them gives the Irishman something to think about for Sunday.

More than the aggregate, that might be what this game becomes about.
