But after Verratti missed his side's extra-time win over Villefranche in the Coupe de France on Wednesday, Tuchel revealed the midfielder had suffered a fresh injury.
"Marco Verratti could not finish training yesterday [Tuesday]. He had problems," he said.
"I have to wait until tomorrow [Thursday] to decide if he can play against Bordeaux.
"His new problem is something else, but I do not know too much."
PSG host Bordeaux on Saturday before making the trip to Old Trafford for the first leg of their tie with United three days later.
