PSG's Saturday match away to Strasbourg was postponed because of fears of the spreading coronavirus in the region.
"It was negative for me because we flew to Strasbourg," said PSG manager Thomas Tuchel. "We were in Strasbourg and we couldn't play. It was a last test for this game on Wednesday [against Borussia Dortmund] without any problem to adapt to the workload and the intensity of this game [that is coming up]."
Elsewhere in France, Metz have confirmed that they have quarantined an unnamed player after they recently came into contact with somebody who has been diagnosed with the coronavirus.
The Ligue 1 side said that the player is showing no symptoms but has been asked to stay home for now.

Tuchel added: "And yes, with all the news about the coronavirus, with Kylian Mbappe now, we have a lot of things to think about, a lot of things to adapt to. But at the same time, it is a football match and we must adapt.
"I really hope we are capable of adapting, we have a lot of confidence we can adapt. But the difference is too big to talk about it. It's huge."
