Raheem Sterling joined Feyenoord as a free agent earlier in February, but was forced to train in Belgium as he waited to receive a work permit.
Robin van Persie and Feyenoord moved their training to Belgium this week to join Sterling in Tubize, where the Belgian Football Association's training complex is situated.
The 82-time England international is now set to potentially debut for Feyenoord as early as Saturday, when the Rotterdam giants host promoted outfit Telstar in De Kuip.
