As some others have said it's a difficult job to find a manager in March who can both satisfy the requirement to firm us up defensively and keep us up. Then also be the man we want for the future build of the team.
There will be more managers available, or prepared to leave clubs at the end of the season in May.
So, for me, if no 100% ideal candidate I would prefer we go with Robinson until season end then move fairly quickly to appoint a long term manager. Unless, for example, there is an outstanding candidate ready to come in and do a 3 month shift for us.
If we do go with Robinson full perm manager I would be surprised as he is inexperienced and basically unproven. If he keeps us up however I wouldn't be surprised to see him given the gig.
