Matters little really where he goes on trial Wednesday or otherwise. He's been here for a few years in the u23/21s and not really got close to the 1st team. He was promising a few years ago and clearly has some skill/ability on free kicks but loaned out to a tier 6 side and was not able to be a regular.
I expect with so many others like Jebbison, Osula, Arblaster, Peck, Brooks, Maguire and now Marsh there is just not room and the coaching staff have probably told him he is free to find a new club. They'll be others (Hackford seems to have disappeared without trace despite a few injuries) who will move on too.
We can't keep them all and not all will go on to be stars. The majority from our u21/18 won't even be League footballers in 3-4 years as harsh as that is. If we get a few to come through that's a success.
As others have said if he did not have an exotic name (involved with Tunisia junior National teams) not sure there would be such a fuss?
