What Rangers must do with these five rising stars after Caixinha revolution
Aidan Wilson
Wilson is a difficult one. Making two appearances for Rangers last season, the 18-year-old impressed against Aberdeen and St. Johnstone.
However, the Gers have plenty of competition at centre-back following the arrival of Alves and Cardoso, while Rob Kiernan, Danny Wilson and David Bates still remain in Glasgow.
If the Gers sell fringe star Kiernan, then keeping Wilson could be crucial in providing cover for the first team but a loan is most beneficial for the five-time Scotland Under-17 international.
