Raphinha was left out of the squad for the trip to Australia.
On Sunday, the team will leave for the Gold Coast to play against Villa, and then on to Perth to play Crystal Palace.
Raphinha was signed from Rennes for 17 million dollars two years ago.
Jesse Marsch said there was an urgent need from Raphinha to find a solution after the game.
"Raphinha has hopes and dreams and we will see how they go." He said he knows he loves the team and the club.
We will see how it goes. We have to wait and see what happens. He needs to come up with a solution.
Archie Gray, the grandson and son of former Scotland internationals Frank and Andy Gray, is one of the six new signings.
Junior Firpo is not in the squad.
