There was a team of French out of contract players over training and staying at the University of Stirling last week and they played a series of bounce games, one of which was against Alloa and was being watched by many professional teams. I might be wrong but I think they beat Alloa 3-1.
I'm guessing the trialists were picked up from there with the obvious exception of Longrdige and Djorkaeff. If they showed up well in those bounce games then they were worth a look in amongst the squad. By all accounts none of them were good enough so we move on, nothing to worry about.
