Lewandowski missed the 2-1 loss to Netherlands in Poland's Group D opener after injuring his thigh in his side's final warm-up game.

The Barcelona striker was always expected to miss that game but was given a chance of playing against Austria in Berlin after taking part in team training.

Probierz confirmed on the eve of the crucial showdown that "all players" are available, but could not say whether Lewandowski will start.

"There is a big difference if you have best player in the world on the bench or you have him on the pitch," Probierz said. 

"We will make a decision later today. I hope the decision is positive and I hope I can select him tomorrow. We still don't know. 

"I am waiting for the medical team to take the decision. Practically all players will appear in training and a decision will be taken after that.”

Lewandowski has made more appearances (150) and scored more goals (82) for Poland than any other player.
