Rangers have taken Brazilian midfielder Andre Moritz and former France under-20 defender Sebastien Faure on trial.
Moritz has an Italian passport and would not need a work permit and would come as a free agent.
The 26-year-old has spent five years in Turkish football with Kasimpasa, Kayserispor and Mersin Idmanyurd.
Faure, 21, was released by Lyon at the end of last season and had a trial spell at Championship Leeds last month. He has returned to Murray Park after training with Rangers last week.
