I'm sure all three had opportunities to go out on loan but instead play with the u21s, not exactly setting the greatest example
Kozak has a squad number and maybe looked at Gestede and thought "if he's getting a game then there's no reason why I can't"
Footballer having confidence in his own ability shocker. Maybe he wanted to stay at Villa because he trusted the medical staff at BH to work with him to complete his rehab. Maybe he went to Glasgow and thought "f##k this."
I can't recall any mention of loan enquiries for the Senderos and N'Zogbia was rumoured to be on his way to one of the gulf states, in which case I can't blame him for not going.
