The Falconets had resumed camp on Monday and held their first full training session with a full squad on Wednesday afternoon at the Fifa Goal Project, Abuja.
Captain Kemi Famuditi, Charity Rueben and team's top scorer Rasheedat Ajibade were part of the training session as they gear up for the double-legged encounter with Basetsana.
With this development, Christopher Danjuma's side will certainly be spending their Christmas at the Serob Hotel to continue their one-session daily training until January.
